We set the output directory to the git subdirectory prefix if one has
not already been specified. However, in the case of --stdout, we
explicitly _don't_ want the output directory to be set. The result was
that "git-format-patch --stdout" in a directory besides the project root
produced the "standard output, or directory, which one?" error message.

Its possible for external programs to update file modification dates of
many files within a repository. I've seen this on Windows with a popular
virus scanner, sadly enough. If the user has Trust File Modification
Timestamp enabled and the virus scanner touches a large number of files
it can be annoying trying to clear them out of the 'Changed But Not
Updated' file list by clicking on them one at a time to load the diff.
So now we force a rescan as soon as one such file is found, and for
just that rescan we disable the Trust File Modification Timestamp option
thereby allowing Git to update the modification dates in the index.

This separates the connectivity check into separate codepaths,
one for reachable objects and the other for unreachable ones,
while adding a lot of comments to explain what is going on.
When checking an unreachable object, unlike a reachable one, we
do not have to complain if it does not exist (we used to
complain about a missing blob even when the only thing that
references it is a tree that is dangling). Also we do not have
to check and complain about objects that are referenced by an
unreachable object.
This makes the messages from fsck-objects a lot less noisy and

Earlier, git_connect() returned the same fd twice or two
separate fds, depending on the way the connection was made (when
we are talking to the other end over a single socket, we used
the same fd twice, and when our end is connected to a pipepair
we used two).
This forced callers who do close() and dup() to really care
which was which, and most of the existing callers got this
wrong, although without much visible ill effect. Many were
closing the same fd twice when we are talking over a single
socket, and one was leaking a fd.
This fixes it to uniformly use two separate fds, so if somebody
wants to close only reader side can just do close() on it
without worrying about it accidentally also closing the writer
side or vice versa.

This reverts commit 9b088c4e39.
Protecting 'mature' objects does not make it any safer. We should
admit that git-prune is inherently unsafe when run in parallel with
other operations without involving unwarranted locking overhead,
and with the latest git, even rebase and reset would not immediately
create crufts anyway.
Marco Candrian noticed that one cat-file example refers to a
blob object that is never used in the example sequence.
The bug is interesting in that the output from the botched

I refactored the common code related to tracking branch listing into

Some of my file paths in some of my repositories are very long, this

package structure and then the file name itself is rather long and

Now we draw both horizontal and vertical scrollbars for both file lists,

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.

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.

Using a stack of frames in the Starting Revision section of the new

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.

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

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 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.

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.

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.

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.

We now need to keep track of which side the current diff is for,
HEAD<->index or index<->working directory. Consequently we need

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
