git-gui: remove unused git-version

git-version supports choosing different bodies of code passed into it,
rather than using the more traditional if/else construct typically used.
The only use of git-version in this mode was by its author in 2007, and
that code has been deleted.  So, delete this now unused function that
was mostly ignored.
