[PATCH v2 0/3] shortlog: disallow left-over arguments outside repo

This is v2 of my attempt at stopping shortlog from BUG-ing when it is used incorrectly outside a repo. Thanks Jonathan and Junio for helpful comments.

Patches 1 and 2 are identical to pu. The error message in patch 3 is now more general. The error condition on the other hand is a bit more specific, "argc > 1", to better match the intention and commit message.
