Subject: [PATCH] Use current-dir as final fallback repo name

It all falls into place! I had been dreading doing this bit, but after
updating the usage guide I realized the CLI args should be split, too.
Which finally means that I can just glue on the PWD name as a final
fallback for the repo name.

Try the args, then the config file(s), then PWD. If nothing works, the
user is in a world of hurt. Bail out.
