My bad, that's still how they're named when using manpages, so that's
what my muscle memory did.

How about this:

The bash completion script knows some options to "git log" and
"git show" only in the positive form, (e.g. "--abbrev-commit"), but not
in their negative form (e.g. "--no-abbrev-commit"). Adds them.

Also, the bash completion script is missing some other options to
"git diff", and "git show" (and thus, all other commands that take
"git diff"'s options). Adds them. Of note, since "--indent-heuristic" is
no longer experimental, adds that too.

Whoops, there doesn't seem to be a way to add that separately from the
commit message in the submitGit interface. I'll try adding it, but
gmail might turn all the tabs into spaces, so if it does, I'll try to
figure out how to resubmit.

I think I'll stick with this patch for now (it's my first!), but I
might come around and do refactoring in a second pass.
