upload-archive: handle "-h" option early
Normally upload-archive forks off upload-archive--writer to do the real work, and relays any errors back over the sideband channel. This is a good thing when the command is properly invoked remotely via ssh or git-daemon. But it's confusing to curious users who try "git upload-archive -h". Let's catch this invocation early and give a real usage message, rather than spewing "-h does not appear to be a git repository" amidst packet-lines. The chance of a false positive due to a real client asking for the repo "-h" is quite small. Likewise, we'll catch "-h" in upload-archive--writer. People shouldn't be invoking it manually, but it doesn't hurt to give a sane message if they do. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
