Because git-gui is actually a project maintained external from
git.git.  It just happens that Junio pulls various versions of
it into git.git to distribute it along with git.git releases.

I deal with these sorts of "atomic changes" by making an evil merge
in git.git and asking Junio to pull the evil merge.  But we've only
had one such case thus far.

(iv) if tclsh is not available then create a simpler lib/tclIndex that
loads all of the lib directory, even if it isn't needed.  That makes
tclsh being available strictly an optimization, and yet git-gui still
is installable.
