What that doesn't give you is the ability to say "git <git-options> diff
<git-diff-options>", which is very nice and makes the inconsistencies I
just posted on less likely.  Fortunately, any getopt-variant can deal with
these; you just have to pass the tail of argv and a suitably reduced value
for argc to another call of the options parser.
