Tab completion works for `git --version`, but not `git version`.
Of course, it would work with a custom executable script git-version on PATH.

Interestingly, it works even if the git-version script is an empty file.

It's because git-version isn't mentioned in "git help -a", from which we
generate the completion list. That comes from command-list.h, which in
turn is generated from command-list.txt, which doesn't mention
git-version as a command. And we can't add it there until it has a
manpage (since we pull the oneline description from the synopsis).

It might not be a bad thing to have a manpage. For example, the
--build-options is undocumented.

cmd_version() is also weirdly in help.c, not builtin/help.c, which might
be worth fixing.
