I am not sure if --short/--porcelain should even be accepted by "git
commit" in the first place.  It used to be that "git status" and
"git commit" were the same program in a different guise and "git
status <anything>" were merely a "git commit --dry-run <anything>",
but the recent push is in the direction of making them totally
separate in the end-user's minds.  So if we want a proper fix, I
would actually think that these options should *error out* at the
command line parser level, way before checking if there is anything
to commit.
