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.

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
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.

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.

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
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.

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.

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
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

Its possible for the user to select a branch for the merge test
(while deleting branches) and also select that branch for deletion.
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
skip over a branch and not delete it if that is the branch which
the user selected for the merge check.

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.

The only reason the commit_prehook logic was broken out into its own

Rather than relying on the file state and just inverting it, we should

Users often forget to repack their object database, then start to
complain about how slow it is to perform common operations after
they have collected thousands of loose objects in their objects
directory. A simple repack usually restores performance.
During startup git-gui now asks git-count-objects how many loose
objects exist, and if this number exceeds a hardcoded threshold
we suggest that the user compress the database (aka run 'git gc')
at this time. I've hardcoded this to 2000 objects on non-Windows
systems as there the filesystems tend to handle the ~8 objects
per directory just fine. On Windows NTFS and FAT are just so slow
