Its useful to be able to amend the last commit even if it was a merge
commit, so we really should support that in the gui. We now do so by
making PARENT a list. We always diff against the first parent but we
create a commit consisting of the parent(s) listed in this list, in
order.
We also should recheck the repository state during an amend. Earlier
I was bitten by this exact bug when I switched branches through a
command prompt and then did not do a rescan in git-gui. When I hit
"Amend Last Commit" I was surprised to see information from the prior
branch appear. This was due to git-gui caching the data from the last
rescan and using that data form the amend data load request, rather than
the data of the current branch.
Improved error text in the dialogs used to tell the user why an amend is
being refused by git-gui. In general this is only during an initial
commit (nothing prior to amend) and during a merge commit (it is simply
too confusing to amend the last commit while also trying to complete a
merge).
Fixed a couple of minor bugs in the pull logic. Since this code isn't
really useful nobody has recently tested it and noticed the breakage.
It really needs to be rewritten anyway.

An earlier commit b37a562a added a check to see if the ref
points at a valid object (as a part of 'negative ref' support
which we currently do not use), but did so only while iterating
over both packed and loose refs, and forgot to apply the same
check while iterating over the remaining ones.
We might want to replace the "if null then omit it" check with
"eh --- what business does a 0{40} value have here?" complaint
later since we currently do not use negative refs, but that is
a separate issue.

In order to allow the user to toggle include/exclude from next commit
for files which were partially included in the last commit we need the
current index mode+sha1 data stored in our file_states array. For
any partially included file we have this information from diff-files,
so we just have to copy it over to the diff-index portion of our state
array.

The tags used for diff formatting (which I inherited from gitool) just
didn't make a whole lot of sense, especially if you wanted to try to
match them to the diff output you were seeing on screen. It did not
help that the diff-index -c output's first two columns are also munged
to make the diff output more user friendly.
So this is a large refactoring of the tags used for diff display. Now
our tag names match what we put in the left column of each line, which
makes it easier to correlate presentation and implementation.
I removed bold font usage from everything except the hunk headers as I
really did not like the way bold font caused column alignments to become
out of whack within the diff viewer. It also drew attention to the parts
of the file which were identically changed in both the index and in the
working directory, yet these are usually the parts I find myself caring
the least about. So its very counter-intuitive.
Lines which are changed differently by both the index and the working
directory are now shown with background colors which span the entire line,
making these lines easier to pick out of the diff. In general these are
the lines that appear to be more interesting to me when looking at the
3-way diff as they are the ones which contain recent and quite different
changes.

New files also lack index data from diff-files therefore we cannot use
their diff-files index data when we update-index. Instead we can use
the fact that Git has them hardcoded as "0 0{40}" and do the same thing
ourselves. This way you can toggle an untracked file into added status
and back out to untracked.

Currently core-git's diff utilities report a deleted symlink as a
deleted file with a mode of 120000. This is not nearly as user
friendly as one might like, as the user must remember that 120000
is the UNIX mode bits for a symlink. So instead we transform
the not-so-friendly message from core-git into a slightly more
user friendly "deleted symlink" message.

Tcl let me assign two different types of values to the variable $n.
Prior to 1461c5f3 $n was the total number of bytes in the string;
but in that commit it also became the current info list for the
current file. This caused $c < $n to fail as $n was now treated
as 0 and we only loaded the first file in each buffer.
So use a different variable, like $i, instead.

There was a bug with the way we handled deleted file status. A file

The previous implementation of do_include_selection did not actually
add files in state _O (untracked, not added) into the repository when
they were in the selection and Commit->Include Selected Files was used.
This was due to the file state filtering logic being the same as that
of Commit->Include All Files, which only considers existing files.
Also fixed a minor issue with rejected attempts to amend an initial

Its not an error that a rescan is required before commit; its just
something we do as a safety feature to try and ensure the user knows
what is going into this commit. So the dialog should use the info
icon (if one is used by the host OS) rather than the error icon.
Its also not "highly likely" that another Git program modified the
repository, its completely the case. There is no reason why the
repository would not match our last scanned state unless another
Git program modified the repository (or someone else did so by hand).
So don't be vague about it, own up to the issue and go on with our
business.

Since git-commit also checks that the user has a GIT_COMMITTER_IDENT

Because we immediately start a rescan operation, but do so slightly
delayed (by 1 ms, to let the UI show before we start forking off
git processes), we can't let the user try to activate any of the
restricted GUI commands before the 1 ms timer expires and we kick
off the rescan.
So now we lock the index before we enter the Tk event loop, ensuring
that it is impossible for the user to inject a conflicting UI event
before our rescan can begin.

When the user selects a number of files they would typically expect
to be able to act on that selection, such as by including those files
into the next commit.
So we now have a menu option under the Commit menu that lets the user
include only the selection, rather than everything. If there is no
selection but there is a file in the diff viewer than we consider that
to be the selection (a selection of 1). Unfortunately we don't disable
this option yet when there's nothing selected to include, but this is
probably not a big deal as there are very few situations where there
are no selected files.

I noticed that we were reshowing the current diff during a commit;
this occurs because we feed every added and modified file through
update-index just before commit. During the update-index process
we reshow the current diff if the current file in the diff pane
was one of those added or modified files we reprocessed. This
just slows down the UI more than is necessary.
So refactoring update_index so that we don't call reshow_diff
from within that code; instead we do it at a higher level.

Apparently I never really tested the logic for making or amending an
initial commit, so although most of the code was here in git-gui it
didn't quite work as it was intended to.
So this is all just bug fixes to make initial commits correctly
generate the list of files going into the initial commit, or to
show a newly added file's diff, and to amend an initial commit.
Because we really want to diff the index against a tree-ish and
there is no such tree-ish on an initial commit we create an empty
tree through git-mktree and diff against that. This unfortunately
creates a dangling tree, which may confuse a new user who uses
git-gui to make a new commit and then immediately afterwards runs
git fsck-objects to see if their object database is corrupt or not.

Some users may want to start us by running "git --git-dir=... gui"
rather than trying to cd into the directory first. This is especially
true if they want to just make a shortcut to our executable on Windows
and always have that associated with a certain repository.
Since Tcl on Windows throws away our environment and doesn't pass it
down to the child process correctly we cannot call git-rev-parse to
get the GIT_DIR environment variable. So instead we ask for it
specifically ourselves; if its not defined then we ask rev-parse.
