If we generate a blame status string before we have obtained
any annotation data at all from the input file, or if the input
file is empty, our total_lines will be 0. This causes a division
by 0 error when we blindly divide by the 0 to compute the total
percentage of lines loaded. Instead we should report 0% done.

I got a little surprise one day when I tried to run 'git gui version'
outside of a Git repository to determine what version of git-gui was
installed on that system. Turns out we were doing the repository
check long before we got around to command line argument handling.
We now look to see if the only argument we have been given is
'version' or '--version', and if so, print out the version and
exit immediately; long before we consider looking at the Git
version or working directory. This way users can still get to
the git-gui version number even if Git's version cannot be read.

Johannes Sixt noticed that git-gui would not let the user commit
a merge created by `git merge -s ours` as the ours strategy does
not alter the tree (that is HEAD^1^{tree} = HEAD^{tree} after the
merge). The same issue arises from amending such a merge commit.
We now permit an empty commit (no changed files) if we are doing
a merge commit. Core Git does this with its command line based
git-commit tool, so it makes sense for the GUI to do the same.

Mark Levedahl noticed that git-gui will let you create an empty
normal (non-merge) commit if the file state in the index is out
of whack. The case Mark was looking at was with the new autoCRLF
feature in git enabled and is actually somewhat difficult to create.
I found a different way to create an empty commit: turn on the
Trust File Modifications flag, touch a file, rescan, then move
the file into the "Changes To Be Committed" list without looking
at the file's diff. This makes git-gui think there are files
staged for commit, yet the update-index call did nothing other
than refresh the stat information for the affected file. In
this case git-gui allowed the user to make a commit that did
not actually change anything in the repository.
Creating empty commits is usually a pointless operation; rarely
does it record useful information. More often than not an empty
commit is actually an indication that the user did not properly
update their index prior to commit. We should help the user out
by detecting this possible mistake and guiding them through it,
rather than blindly recording it.
After we get the new tree name back from write-tree we compare
it to the parent commit's tree; if they are the same string and
this is a normal (non-merge, non-amend) commit then something
fishy is going on. The user is making an empty commit, but they
most likely don't want to do that. We now pop an informational
dialog and start a rescan, aborting the commit.

cehteh on #git noticed that there was no way to perform a reset --hard
from within git-gui. When I pointed out this was Merge->Abort Merge
cehteh said this is not very understandable, and that most users would
never guess to try that option unless they were actually in a merge.
So Branch->Reset is now also a way to cause a reset --hard from within
the UI. Right now the confirmation dialog is the same as the one used
in Merge->Abort Merge.

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.

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

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

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

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).

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.

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.

Users want to navigate the file list shown in our branch browser

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

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

most files don't have that property.
What we really need to do is look at what colors are used by our

should force our neighbor to recolor too. Yes, its the graph coloring

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.

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.

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.

based on the operating system and the available browsers for each.
We prefer documentation which is installed parallel to Git's own
