8134722306 git-gui: Refactor 'exec git subcmd' idiom.
As we frequently need to execute a Git subcommand and obtain
its returned output we are making heavy use of [exec git foo]
to run foo.  As I'm concerned about possibly needing to carry
environment data through a shell on Cygwin for at least some
subcommands, I'm migrating all current calls to a new git
proc.  This actually makes the code look cleaner too, as
we aren't saying 'exec git' everywhere.

7e81d4eead git-gui: Rename GIT_VERSION to GITGUI_VERSION.
Now that the decision has been made to treat git-gui as a

should use a different substitution for our version value
to avoid any possible confusion.

0960f7d6db git-gui: Stop deleting gitk preferences.
Now that git 1.5.0 and later contains a version of gitk that uses
correct geometry on Windows platforms, even if ~/.gitk exists, we
should not delete the user's ~/.gitk to work around the bug.  It
is downright mean to remove a user's preferences for another app.

486ef5270c git-gui: Improve annotated file display.
Rather than trying to mark the background color of the line numbers
to show which lines have annotated data loaded, we now show a ruler
between the line numbers and the file data.  This ruler is just 1
character wide and its background color is set to grey to denote
which lines have annotation ready.  I had to make this change as I
kept loosing the annotation marker when a line was no longer colored
as part of the current selection.

We now color the lines blamed on the current commit in yellow, the
lines in the commit which came after (descendant) in red (hotter,
less tested) and the lines in the commit before (ancestor) in blue
(cooler, better tested).

1351ba13e5 git-gui: Jump to the first annotation block as soon as its available.
To help clue users into the fact that annotation data arrives
incrementally, and that they should try to locate the region
they want while the tool is running, we jump to the first line
of the first annotation if the user has not already clicked on
a line they are interested in and if the window is still looking
at the very top of the file.

Since it takes a second (at least on my PowerBook) to even generate
the first annotation for git-gui.sh, the user should have plenty of
time to adjust the scrollbar or click on a line even before we get
that first annotation record in, which allows the user to bypass
our automatic jumping.

6910ae80d0 git-gui: Redesign the display of annotated files.
Using 180 columns worth of screen space to display just 20 columns of
file data and 160 columns worth of annotation information is not
practically useful.  Users need/want to see the file data, and have
the anotation associated with it displayed in a detail pane only when
they have focused on a particular region of the file.

Now our file viewer has a small 10-line high pane below the file
which shows the commit message for the commit this line was blamed
on.  The columns have all been removed, except the current line
number column as that has some real value when trying to locate an
interesting block.

To keep the user entertained we have a progress meter in the status
bar of the viewer which lets them know how many lines have been
annotated, and how much has been completed.  We use a grey background
on the line numbers for lines which we have obtained annotation from,
and we color all lines in the current commit with a yellow background,
so they stand out when scanning through the file.  All other lines
are kept with a white background, making the yellow really pop.

df6287ecd7 git-gui: Use git-config now over git-repo-config.
Now that core Git has "renamed" git-repo-config to git-config,
we should do the same.  I don't know how long core Git will
keep the repo-config command, and since git-gui's userbase

or later, where the rename has already taken place, it should
be OK to rename now.

24d2bf2f02 git-gui: Relabel the Add All action.
One user that I spoke with recently was confused why the 'Add All'
button did not add all of his 'Changed But Not Updated' files.
The particular files in question were new, and thus not known to
Git.  Since the 'Add All' routine only updates files which are
already tracked, they were not added automatically.

I suspect that calling this action 'Add Existing' would be less
confusing, so I'm renaming it.

subcommand.

2ebba528dc git-gui: View blame from the command line.
Viewing annotated files is one of those tasks that is relatively
difficult to do in a simple vt100 terminal emulator.  The user
really wants to be able to browse through a lot of information,
and to interact with it by navigating through revisions.

Now users can start our file viewer with annotations by running
'git gui blame commit path', thereby seeing the contents of the
given file at the given commit.  Right now I am being lazy by
not allowing the user to omit the commit name (and have us thus
assume HEAD).

db7f34d4c5 git-gui: Optionally save commit buffer on exit.
If the commit area does not exist, don't save the commit message to
a file, or the window geometry.  The reason I'm doing this is I want
to make the main window entirely optional, such as if the user has
asked us to show a blame from the command line.  In such cases the
commit area won't exist and trying to get its text would cause an
error.

If we are running without the commit message area, we cannot save
our window geometry either, as the root window '.' won't be a normal

9bccb782c3 git-gui: Support keyboard traversal in browser.
Users want to navigate the file list shown in our branch browser
windows using the keyboard.  So we now support basic traversal
with the arrow keys:

  Up/Down:  Move the "selection bar" to focus on a different name.

  Return:   Move into the subtree, or open the annotated file.
  M1-Right: Ditto.

  M1-Up:    Move to the parent tree.
  M1-Left:  Ditto.

Probably the only feature missing from this is to key a leading part
of the file name and jump directly to that file (or subtree).

This change did require a bit of refactoring, to pull the navigation
logic out of the mouse click procedure and into more generic routines
which can also be used in bindings.

37f1db80a4 git-gui: Assign background colors to each blame hunk.
To help the user visually see which lines are associated with each other
in the file we attempt to sign a unique background color to each commit
and then render all text associated with that commit using that color.

This works out OK for a file which has very few commits in it; but
most files don't have that property.

What we really need to do is look at what colors are used by our
neighboring commits (if known yet) and pick a color which does not
conflict with our neighbor.  If we have run out of colors then we
should force our neighbor to recolor too.  Yes, its the graph coloring
problem.

747c0cf93c git-gui: Use a grid layout for the blame viewer.
Using a panedwindow to display the blame viewer's individual columns
just doesn't make sense.  Most of the important data fits within the
columns we have allocated, and those that don't the leading part fits
and that's good enough.  There are just too many columns within this
viewer to let the user sanely control individual column widths.  This
change shouldn't really be an issue for most git-gui users as their
displays should be large enough to accept this massive dump of data.

We now also have a properly working horizontal scrollbar for the
current file data area.  This makes it easier to get away with a
narrow window when screen space is limited, as you can still scroll
around within the file content.

915616e4eb git-gui: Display original filename and line number in blame.
When we annotate a file and show its line data, we're already asking
for copy and movement detection (-M -C).  This costs extra time, but
gives extra data.  Since we are asking for the extra data we really
should show it to the user.

Now the blame UI has two additional columns, one for the original
filename (in the case of a move/copy between files) and one for the
original line number of the current line of code.

35874c163e git-gui: Implemented file browser and incremental blame.
This rather huge change provides a browser for the current branch.  The
browser simply shows the contents of tree HEAD, and lets the user drill
down through the tree.  The icons used really stink, as I just copied in
icon which we already had.  I really need to replace the file_dir and
file_uplevel icons with something more useful.

If the user double clicks on a file within the browser we open it in
a blame viewer.  This makes use of the new incremental blame feature
that Linus just added yesterday to core Git.  Fortunately the feature
will be in 1.5.0 final so we can rely on having it available here.

Since the blame engine is incremental the user will get blame data
for groups which can be determined early.  Git will slowly fill in
the remaining lines as it goes.

20ddfcaa7e git-gui: Test for Cygwin differently than from Windows.
Running on Cygwin is different than if we were running through MinGW.

In the Cygwin case we have cygpath available to us, we need to perform
UNIX<->Windows path translation sometimes, and we need to perform odd
things like spawning our own login shells to perform network operations.
But in the MinGW case these don't occur.  Git knows native Windows file
paths, and login shells may not even exist.

Now git-gui will avoid running cygpath unless it knows its on Cygwin.
It also uses a different shortcut type when Cygwin is not present, and
it avoids invoking /bin/sh to execute hooks if Cygwin is not present.
This latter part probably needs more testing in the MinGW case.

This change also improves how we start gitk.  If the user is on any type
of Windows system its known that gitk won't start right if ~/.gitk exists.
So we delete it before starting if we are running on any type of Windows
operating system.  We always use the same wish executable which launched
git-gui to start gitk; this way on Windows we don't have to jump back to
/bin/sh just to go into the first wish found in the user's PATH.  This
should help on MinGW when we probably don't want to spawn a shell just
to start gitk.

273984fc4f git-gui: Offer quick access to the HTML formatted documentation.
Users may want to be able to read Git documentation, even if they

terms covered within the standard Git documentation which would be

We now try to offer an 'Online Documentation' menu option within the

setup.  We default to instaweb.browser, if set, as this is probably
accurate for the user's configuration.  If not then we try to guess
based on the operating system and the available browsers for each.
We prefer documentation which is installed parallel to Git's own
executables, e.g. `git --exec-path`/../Documentation/index.html, as
that is how I typically install the HTML docs.  If those are not found
then we open the documentation published on kernel.org.

Changed our private merge summary config option to be the same as the

In the same vein I've also added merge.verbosity to the gui options,

merge strategy.  I happen to like level 1 and suggest that other users
use that, but level 2 is the core Git default right now so we'll use
the same default in git-gui.

e4834837a8 git-gui: Implement local merge operations.
To allow users to merge local heads and tracking branches we now offer
a dialog which lets the user select 1-15 branches and merge them using
the stock `git merge` Grand Unified Merge Driver.

Originally I had wanted to implement this merge internally within git-gui
as I consider GUMD to be mostly Porcelain-ish, but the truth is it does
its job exceedingly well and its a relatively complex chunk of code.
I'll probably circle back later and try to remove the invocation of GUMD
from git-gui, but right now it lets me get the job done faster.

Users cannot start a merge if they are currently in the middle of one,
or if they are amending a commit.  Trying to do either is just stupid
and should be stopped as early as possible.

I've also made it simple for users to startup a gitk session prior to
a merge by offering a Visualize button which runs `gitk $revs --not HEAD`,
where $revs is the list of branches currently selected in the merge
dialog.  This makes it quite simple to find out what the damage will
be to the current branch if you were to carry out the currently proposed
merge.

bc7452f5e7 git-gui: Use builtin version of 'git gc'.
Technically the new git-gc command is strictly Porcelain; its invoking
multiple plumbing commands to do its work.  Since git-gui tries to not
rely on Porclain we shouldn't be invoking git-gc directly, instead we
should perform its tasks on our own.

To make this easy I've created console_chain, which takes a list of
tasks to perform and runs them all in the same console window.  If
any individual task fails then the chain stops running and the window
shows a failure bar.  Only once all tasks have been completed will it
invoke console_done with a successful status.

Because I want to be able to run multiple output-producing commands
in a single 'console' window within git-gui I'm refactoring the
console handling routines to require the "after" argument of console_exec.

the first is the console window handle and the second is the status of
the last command (0 on failure, 1 on success).

A new procedure console_done can be passed to the last console_exec
command to forward perform all cleanup and enable the Close button.
Its status argument is used to update the final status bar on the
bottom of the console window.

1d6a978752 git-gui: Added arbitrary branch pushing support.
Because its common for some users to push topic branches to a remote
repository for review and merging by other parties, users need an
easy way to push one or more branches to a remote repository without
needing to edit their .git/config file anytime their set of active
branches changes.

We now provide a basic 'Push...' menu action in the Push menu which
opens a dialog allowing the user to select from their set of local
branches (refs/heads, minus tracking branches).  The user can designate
which repository to send the changes to by selecting from an already
configured remote or by entering any valid Git URL.

156b29211a git-gui: Always use lsearch -exact, to prevent globbing.
Anytime we are using lsearch we are doing [lsearch -sorted] and we
are applying it to file paths (or file path like things).  Its valid
for these to contain special glob characters, but when that happens
we do not want globbing to occur.  Instead we really need exact
match semantics.  Always supplying -exact to lsearch will ensure that
is the case.

5f8b70b1dc git-gui: Maintain the same file list for diff during refresh.
I just noticed that a file was always jumping to compare against HEAD
and the index during a refresh, even if the diff viewer was comparing
the index against the working directory prior to the refresh.  The
bug turned out to be caused by a foreach loop going through all file
list names searching for the path.  Since $ui_index was the first one
searched and the file was contained in that file list the loop broke
out, leaving $w set to $ui_index when it had been set by the caller
to $ui_workdir.  Silly bug caused by using a parameter as a loop
index.

3f7fd924a9 git-gui: Remove Pull menu and cleanup Branch/Fetch/Push menus.
The Pull menu as it stands right now is a really horrible idea.  Most
users will have too many branches show up in this menu, and what with
the new globbing syntax for fetch entries we were offering up possible
merging that just isn't really valid.  So this menu is dead and will
be rewritten to support better merge capabilities.

The Branch menu shouldn't include a separator entry if there are no
branches, it just looks too damn weird.  This can happen in an initial
repository before any branches have been created and before the first
commit.

The Fetch and Push menus should just be organized around their own
menus rather than being given the menu to populate.

4e55d19a13 git-gui: Cleanup end-of-line whitespace in commit messages.
When committing changes its useless to have trailing whitespace on the
end of a line within the commit message itself; this serves no purpose
beyond wasting space in the repository.  But it happens a lot on my

it into git-gui.

We now clip any trailing whitespace from the commit buffer when loading
it from a file, when saving it out to our backup file, or when making
the actual commit object.

I also fixed a bug where we lost the commit message buffer if you quit
without editing the text region.  This can happen if you quit and restart
git-gui frequently in the middle of an editing session.

30b14ed390 git-gui: Elide CRs appearing in diff output from display.
If we are displaying a diff for a DOS-style (CRLF) formatted file then
the Tk text widget would normally show the CR at the end of every line;
in most fonts this will come out as a square box.  Rather than showing
this character we'll tag it with a tag which forces the character to
be elided away, so its not displayed.  However since the character is
still within the text buffer we can still obtain it and supply it over
to `git apply` when staging or unstaging an individual hunk, ensuring
that the file contents is always fully preserved as-is.

a25c518933 git-gui: Allow staging/unstaging individual diff hunks.
Just like `git-add --interactive` we can now stage and unstage individual
hunks within a file, rather than the entire file at once.  This works
on the basic idea of scanning backwards from the mouse position to
find the hunk header, then going forwards to find the end of the hunk.
Everything in that is sent to `git apply --cached`, prefixed by the
diff header lines.

We ignore whitespace errors while applying a hunk, as we expect the
user's pre-commit hook to catch any possible problems. This matches
our existing behavior with regards to adding an entire file with
no whitespace error checking.

Applying hunks means that we now have to capture and save the diff header
lines, rather than chucking them.  Not really a big deal, we just needed
a new global to hang onto that current header information.  We probably
could have recreated it on demand during apply_hunk but that would mean
we need to implement all of the funny rules about how to encode weird
path names (e.g. ones containing LF) into a diff header so that the
`git apply` process would understand what we are asking it to do.  Much
simpler to just store this small amount of data in a global and replay
it when needed.

I'm making absolutely no attempt to correct the line numbers on the
remaining hunk headers after one hunk has been applied.  This may
cause some hunks to fail, as the position information would not be
correct.  Users can always refresh the current diff before applying a
failing hunk to work around the issue.  Perhaps if we ever implement
hunk splitting we could also fix the remaining hunk headers.

Applying hunks directly means that we need to process the diff data in
binary, rather than using the system encoding and an automatic linefeed
translation.  This ensures that CRLF formatted files will be able to be
fed directly to `git apply` without failures.  Unfortunately it also means
we will see CRs show up in the GUI as ugly little boxes at the end of
each line in a CRLF file.

Its nice to know how many loose objects and roughly how much disk space
they are taking up, so that you can guestimate about when might be a

especially once the automatic keep-pack code in git-fetch starts to
be more widely used.

We now offer the output of count-objects -v in a nice little dialog
hung off the Repository menu.  Our labels are slightly more verbose
than those of `count-objects -v`, so users will hopefully be able
to make better sense of what we are showing them here.

We probably should also offer pack file size information, and data
about *.idx files which exist which lack corresponding *.pack files
(a situation caused by the HTTP fetch client).  But in the latter
case we should only offer the data once we have way to let the user
clean up old and inactive index files.

59885273c3 git-gui: Handle commit encoding better.
Git prefers that all log messages are encoding in UTF-8.  So now when
git-gui generates the commit message it converts the commit message
text from the internal Tcl Unicode representation into a UTF-8 file.
The file is then fed as stdin to git-commit-tree.  I had to start
using a file here rather than feeding the message in with << as
<< uses the system encoding, which we may not want.

When we reload a commit message via git-cat-file we are getting the
raw byte stream, with no encoding performed by Git itself.  So unless
the new 'encoding' header appears in the message we should probably
assume it is utf-8 encoded; but if the header is present we need to
use whatever it claims.

19b41e4559 git-gui: Limit display of large untracked files.
Our internal diff viewer displays untracked files to help users see if
they should become tracked, or not.  It is not meant as a full file
viewer that handles any sort of input.  Consequently it is rather
unreasonable for users to expect us to show them very large files.
Some users may click on a very big file (and not know its very big)
then get surprised when Tk takes a long time to load the content and
render it, especially if their memory is tight and their OS starts to
swap processes out.

Instead we now limit the amount of data we load to the first 128 KiB
of any untracked file.  If the file is larger than 128 KiB we display
a warning message at the top of our diff viewer to notify the user
that we are not going to load the entire thing.  Users should be able
to recognize a file just by its first 128 KiB and determine if it
should be added to the repository or not.

Since we are loading 128 KiB we may as well scan it to see if the
file is binary.  So I've removed the "first 8000 bytes" rule and
just allowed git-gui to scan the entire data chunk that it read in.
This is probably faster anyway if Tcl's [string range] command winds
up making a copy of the data.

core Git uses; if there is a NUL byte (\0) within the first 8000 bytes
of the file we assume it is binary and refuse to show the content.

Given that we have loaded the entire content of the file into memory
we probably could just afford to search the whole thing, but we also
probably should not load multi-megabyte binary files either.

124355d32c git-gui: Always start a rescan on an empty diff.
If we got an empty diff its probably because the modification time of
the file was changed but the file content hasn't been changed.  Typically
this happens because an outside program modified the file and git-gui
was told to not run 'update-index --refresh', as the user generally
trusts file modification timestamps.  But we can also get an empty diff
when a program undos a file change and still updates the modification
timestamp upon saving, but has undone the file back to the same as what
is in the index or in PARENT.

So even if gui.trustmtime is false we should still run a rescan on
an empty diff.  This change also lets us cleanup the dialog message
that we show when this case occurs, as its no longer got anything to
do with Trust File Modification Timestamps.

ca52156618 git-gui: Make diff viewer colors match gitk's defaults.
Because users who use git-gui are likely to also be using gitk, we
should at least match gitk's default colors and formatting within the
diff viewer.

Unfortunately this meant that I needed to change the background colors
of the hunks in a 'diff --cc' output, as the green used for 'added line'
was completely unreadable on the old color.  We now use ivory1 to show
hunks which came from HEAD/parent^1, which are the portions that the
current branch has contributed, and are probably the user's own changes.
We use a very light blue for the portions which came from FETCH_HEAD,
as this makes the changes made by the other branch stand out more in the
diff.

I've also modified the hunk header lines to be blue, as that is how gitk
is showing them.

Apparently I forgot to raise the sel tag above everything else in the
diff viewer, which meant that selections in the diff viewer were not
visible if they were made on a 'diff --cc' hunk which had a background.
Its now the higest priority tag, ensuring the selection is always visible
and readable.

37d2a1c9fa git-gui: Correctly ignore '* Unmerged path' during diff.
If a path is really unmerged, such as because it has been deleted and
also modifed, we cannot obtain a diff for it.  Instead Git is sending
back '* Unmerged path <blah>' for file <blah>.  We should display this
line as-is as our tag selecting switches don't recognize it.

15e1374927 git-gui: Improve the merge check interface for branch deletion.
Just like how we split out the local and remote branches into two
different pick lists for branch creation, we should do the same
thing for branch deletion.  This means that  there are really 3
modes of operation here:

  * delete only if merged into designated local branch;
  * delete only if merged into designated tracking (remote) branch;
  * delete no matter what

So we now use radio buttons to select between these operations.

We still default to checking for merge into the current branch,
as that is probably the most commonly used behavior. It also is
what core Git's command line tools do.

66cc17d1d3 git-gui: Use a grid layout for branch dialog.
Using a stack of frames in the Starting Revision section of the new
branch dialog turned out to be a mess.  The varying lengths of each
label caused the optionMenu widgets to be spread around the screen
at unaligned locations, making the interface very kludgy looking.

Now we layout the major sections of the branch dialog using grid
rather than pack, allowing these widgets to line up vertically in
a nice neat column.  All extra space is given to column 1, which is
where we have located the text fields.

f8a1518d06 git-gui: Pad new branch name input box.
The new branch name input box was showing up too close to the labelframe
border, it was basically right on top of it on Windows.  This didn't
look right when compared to the Starting Revision's expression input
field, as that had a 5 pixel padding.

So I've put the new name input box into its own frame and padded that
frame by 5 pixels, making the UI more consistent.

14efcc7485 git-gui: Correct unmerged file detection at commit time.
Its impossible to commit an index which has unmerged stages.

Unfortunately a bug in git-gui allowed the user to try to do exactly that,
as we broke out of our file scanning loop as soon as we found a valid AMD
index state.  That's wrong, as the files are coming back from our array
in pseudo-random order; an unmerged file may get returned only after all
merged files.

I also noticed the grammer around here in our dialog boxes still used
the term 'include', so this has been updated to reflect current usage.

68c30b4af1 git-gui: Add Refresh to diff viewer context menu.
Sometimes you want to just force the diff to redisplay itself without
rescanning every file in the filesystem (as that can be very costly
on large projects and slow operating systems).  Now you can force a
diff-only refresh from the context menu.  Previously you could also
do this by reclicking on the file name in the UI, but it may not be
obvious to all users, having a context menu option makes it more
clear.

A prior commit tried to use the old index state for the old working
directory state during a UI refresh of a file.  This caused files
which were being unstaged (and thus becoming unmodified) to drop
out of the working directory side of the display, at least until
the user performed a rescan to force the UI to redisplay everything.

6bdc929984 git-gui: Clear diff from viewer if the side changed.
If the user switches the currently shown file from one side of the UI
to the other then how its diff is presented would be different.  And
leaving the old diff up is downright confusing.

Since the diff is probably not interesting to the user after the switch
we should just clear the diff viewer.  This saves the user time, as they
won't need to wait for us to reload the diff.

079d0d5057 git-gui: Fix bug in unmerged file display.
We were not correctly setting the old state of an index display to
_ if the index was previously unmerged.   This caused us to try and
update a U->M when resolving a merge conflict but we were unable to
do so as the icon did not exist in the index viewer.  Tk did not
like being asked to modify an icon which was undefined.

Now we always transform both the old and the new states for both
sides (index and working directory) prior to updating the UI.

fec4a78590 git-gui: Improve diff --cc viewing for unmerged files.
Now that we are using 'git diff' to display unmerged working directory
files we are getting 'diff --cc' output rather than 'diff --combined'
output.  Further the markers in the first two columns actually make
sense here, we shouldn't attempt to rewrite them to something else.

I've added 'diff --cc *' to the skip list in our diff viewer, as that
particular line is not very interesting to display.

I've completely refactored how we perform detection of the state of a
line during diff parsing; we now report an error message if we don't
understand the particular state of any given line.  This way we know
if we aren't tagging something we maybe should have tagged in the UI.

I've also added special display of the standard conflict hunk markers
(<<<<<<<, =======, >>>>>>>).  These are formatted without a patch op
as the patch op is always '+' or '++' (meaning the line has been added
relative to the committed state) and are displayed in orange bold text,
sort of like the @@ or @@@ marker line is at the start of each hunk.

In a 3 way merge diff hunks which came from our HEAD are shown with a
azure2 background, and hunks which came from the incoming MERGE_HEAD
are displayed with a 'light goldenrod yellow' background.  This makes
the two different hunks clearly visible within the file.  Hunks which
are ++ or -- (added or deleted relative to both parents) are shown
without any background at all.

3b4db3c1a3 git-gui: Improve the display of merge conflicts.
If a file has a merge conflict we want it to show up in the 'Changed
But Not Updated' file list rather than the 'Changes To Be Committed'
file list.  This way the user can mostly ignore the left side (the
HEAD<->index comparsion) while resolving a merge and instead focus
on the merge conflicts, which are just shown on the right hand side.

This requires detecting the U state in the index side and drawing
it as though it were _, then forcing the working directory side to
have a U state.  We have to delay this until presentation time as
we don't want to change our internal state data to be different
from what Git is telling us (I tried, the patch for that was ugly
and didn't work).

When showing a working directory diff and its a merge conflict we
don't want to use diff-files as this would wind up showing any
automatically merged hunks obtained from MERGE_HEAD in the diff.
These are not usually very interesting as they were completed by
the system.  Instead we just want to see the conflicts.  Fortunately
the diff porcelain-ish frontend (aka 'git diff') detects the case of
an unmerged file and generates a --cc diff against HEAD and MERGE_HEAD.
So we now force any working directory diff with an index state of 'U'
to go through that difference path.

82cb8706bb git-gui: Remove combined diff showing behavior.
The combined diff format can be very confusing, especially to new users
who may not even be familiar with a standard two way diff format.  So
for files which are already staged for commit and which are modifed in
the working directory we should show two different diffs, depending on
which side the user clicked on.

If the user clicks on the "Changes To Be Committed" side then we should
show them the PARENT<->index difference.  This is the set of changes they
will actually commit.

If the user clicks on the "Changed But Not Updated" side we should show
them the index<->working directory difference.  This is the set of changes
which will not be committed, as they have not been staged into the index.
This is especially useful when merging, as the "Changed But Not Updated"
files are the ones that need merge conflict resolution, and the diff here
is the conflict hunks and/or any evil merge created by the user.

20a53c029e git-gui: Refactor current_diff -> current_diff_path.
We now need to keep track of which side the current diff is for,
HEAD<->index or index<->working directory.  Consequently we need
an additional "current diff" variable to tell us which side the
diff is for.  Since this is really only necessary in reshow_diff
I'm going to declare a new global, rather than try to shove both
the path and the side into current_diff.

To keep things clear later on, I'm renaming current_diff to
current_diff_path.  There is no functionality change in this
commit.

Its possible for the user to select a branch for the merge test

Doing so would have bypassed our merge check for that branch, as
a branch is always a strict subset of itself.  So we will simply

the user selected for the merge check.

4f9d8519fb git-gui: Improve the branch delete confirmation dialogs.
If the user is deleting a branch which is fully merged into the
selected test branch we should not confirm the delete with them,
the fact that the branch is fully merged means we can recover the
branch and no work will be lost.

If a branch is not fully merged, we should warn the user about which
branch(es) that is and continue deleting those which are fully merged.

We should only delete a branch if the user disables the merge check,
and in that case we should confirm with the user that a delete should
occur as this may cause them to lose changes.
