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).
