There are multiple commands already having this kind of short-long
option completion. The "-c" options of commit, switch and checkout
each have longer counterparts, and both the short and long versions
have completion support for their arguments.

I think these cases are not too frequent, so it doesn't seem to be a
big scaling problem.

Thanks, I'll fix it.

Thanks, I'll fix it.
By the way, I copied this piece of code from _git_switch (it's also
there in _git_checkout), so these problems have to be fixed there as
well.
Also, reading _git_commit it looks that we already have a "$prev"
variable, so I'll use that instead of "$prevword".
