[PATCH] git-gui: Handle git versions of the form n.n.n.GIT

The git-gui version check doesn't handle versions of the form
n.n.n.GIT which you can get by installing from an tarball produced by
git-archive.

Without this change you get an error of the form:
'Error in startup script: expected version number but got "1.5.3.GIT"'

I have a machine on which git was installed from a tarball created by 
running git-archive on master (so a 1.5.3ish version).

When I try running git-gui I get an error message:

'Error in startup script: expected version number but got "1.5.3.GIT"'

followed by what I assume is a code snippet where it failed (I wouldn't 
know tcl if it hit me with a large brick).

Is this expected? driver error? or maybe a bug?

Well, whichever it is, this seems to fix it for me ... with the proviso that I
still no nothing about tcl.  I am also not sure if it is correct to do the
patch against the git repo?
