[TopGit PATCH] Require an argument to tg -r

From: martin f. krafft <madduck@debian.org>
Date: Nov 20, 2008, 12:08 UTC
Message-ID: <1227182937-25056-1-git-send-email-madduck@debian.org>

Right now, if -r is passed to tg, an ugly shift error occurs. This patch checks for that case and outputs the help message if it occurs.
