Subject: tg help: <something>: improve readability
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=topgit.git;a=commitdiff_plain;h=0afdf90c385a5bc7948fea9f1ac119b6259e55c1;ds=sidebyside

tg help: <something>: improve readability

Previously tg help was not showing Usage line, and with this change, now it
looks like e.g.:

$ tg help import
Usage: tg [...] import [-p PREFIX] RANGE...

        Import commits within the given revision range into TopGit,
        creating one topic branch per commit, the dependencies forming
        a linear sequence starting on your current branch.

        The branch names are auto-guessed from the commit messages
        and prefixed by t/ by default; use '-p PREFIX' to specify
        an alternative prefix (even an empty one).
