Subject: Require an argument to tg -r
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=topgit.git;a=commitdiff_plain;h=c7692a249e6ed4cac8efd97279aee1023a6adf3b

Require an argument to tg -r

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.
