9b28a8b9c2 git-gui: Relocate the menu/transport menu code.
This code doesn't belong down in the main window UI creation,
its really part of the menu system and probably should be
located with it.  I'm moving it because I could not find
the code when I was looking for it earlier today, as it was
not where I expected it to be found.

92446aba47 Don't modify CREDITS-FILE if it hasn't changed.
We should always avoid rewriting a built file during `make install`
if nothing has changed since `make all`.  This is to help support
the typical installation process of compiling a package as yourself,
then installing it as root.

Forcing CREDITS-FILE to be always be rebuilt in the Makefile means
that CREDITS-GEN needs to check for a change and only update
CREDITS-FILE if the file content actually differs.  After all,
content is king in Git.

981193786f git-gui: Don't crash in citool mode on initial commit.
Attempting to use `git citool` to create an initial commit caused
git-gui to crash with a Tcl error as it tried to add the newly
born branch to the non-existant branch menu.  Moving this code
to after the normal commit cleanup logic resolves the issue, as
we only have a branch menu if we are not in singlecommit mode.

7391b2e999 git-gui: Remove TODO list.
I'm apparently not very good at keeping my own TODO file current.
I its also somewhat strange to keep the TODO list as part of the
software branch, as its meta-information that is not directly
related to the code.  I'm pulling the TODO list from git-gui and
moving it into a seperate branch.

ee40599330 git-gui: Use mixed path for docs on Cygwin.
The Firefox browser requires that a URL use / to delimit directories.
This is instead of \, as \ gets escaped by the browser into its hex
escape code and then relative URLs are incorrectly resolved, Firefox
no longer sees the directories for what they are.  Since we are
handing the browser a true URL, we better use the standard / for
directories.

372ef954a1 git-gui: Correct crash when saving options in blame mode.
Martin Waitz noticed that git-gui crashed while saving the user's
options out if the application was started in blame mode.  This
was caused by the do_save_config procedure invoking reshow_diff
incase the number of context lines was modified by the user.
Because we bypassed main window UI setup to enter blame mode we
did not set many of the globals which were accessed by reshow_diff,
and reading unset variables is an error in Tcl.

Aside from moving the globals to be set earlier, I also modified
reshow_diff to not invoke clear_diff if there is no path currently
in the diff viewer.  This way reshow_diff does not crash when in
blame mode due to the $ui_diff command not being defined.

26370f73c0 git-gui: Prefer version file over git-describe.
Some distributions are using Git for part of their package
management system, but unpack Git's own source code for
delivery from the .tar.gz.  This means that when we walk
up the directory tree with git-describe to locate a Git
repository, the repository we find is for the distribution
and *not* for git-gui.  Consequently any tag we might find
there is bogus and does not apply to us.

In this case the version file should always exist and be
readable, as the packager is working from the released
.tar.gz sources.  So we should always favor the version
file over anything git-describe guess for us.

I started to find it confusing that git-gui would refer to itself
as git-citool when it was started through the citool hardlink, or
with the citool subcommand.  What was especially confusing was the
options dialog and the about dialog, as both seemed to imply they
were somehow different from the git-gui versions.  In actuality
there is no difference at all.

Now we just call our options menu item 'Options...' (skipping the
application name) and our About dialog now always shows git-gui
within the short description (above the copyleft notice) and in
the version field.

cdf6e08880 git-gui: Permit merging tags into the current branch.
It was pointed out on the git mailing list by Martin Koegler that
we did not show tags as possible things to merge into the current
branch.  They actually are, and core Git's Grand Unified Merge
Driver will accept them just like any other commit.

So our merge dialog now requests all refs/heads, refs/remotes and
refs/tags named refs and attempts to match them against the commits
not in HEAD.  One complicating factor here is that we must use the
%(*objectname) field when talking about an annotated tag, as they
will not appear in the output of rev-list.

54acdd95b8 git-gui: Basic version check to ensure git 1.5.0 or later is used.
This is a very crude (but hopefully effective) check against the
`git` executable found in our PATH.  Some of the subcommands and
options that git-gui requires to be present to operate were created
during the 1.5.0 development cycle, so 1.5 is the minimum version
of git that we can expect to support.

There actually are early releases of 1.5 (e.g. 1.5.0-rc0) that
don't have everything we expect (like `blame --incremental`) but
these are purely academic at this point.  1.5.0 final was tagged
and released just a few hours ago.  The release candidates will
(hopefully) fade into the dark quickly.

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.

Probably the only feature missing from this is to key a leading part

displays should be large enough to accept this massive dump of data.

narrow window when screen space is limited, as you can still scroll

db45378165 git-gui: Allow users to edit user.name, user.email from options.
Users may need to be able to alter their user.name or user.email
configuration settings.  If they are mostly a git-gui user they
should be able to view/set these important values from within
the git-gui environment, rather than needing to edit a raw text
file on their local filesystem.

c94dd1c8c2 git-gui: Display the current branch name in browsers.
Rather than using HEAD for the current branch, use the actual name of
the current branch in the browser.  This way the user knows what a
browser is browsing if they open up different browsers while on different
branches.

3eddda9843 git-gui: Improve the icons used in the browser display.
Real icons which seem to indicate going up to the parent (an up arrow)
and a subdirectory (an open folder).  Files are now drawn with the
file_mod icon, like a modified file is.  This just looks better as it
is more consistent with the rest of our UI.

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.
