Subject: Don't implement the usage message of tg depend more than once
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=1b5ad09b5bf411f83c0e20ed5cf6ac02f06b940f;p=topgit.git

Don't implement the usage message of tg depend more than once

The implmentation of "tg depend" had the usage message in two places.
Fixed by creating a usage function, so that there is a single place
to edit if the usage changes.
