  Looks mostly good. Can you rebase this onto the current tip and update the
  help?

  It's probably better to leave the existing tests to test the old behavior
  by adding some arguments (maybe `-r tip:0`) unless we're sure that the new
  behavior covers things that should be tested.

  Nit: If you want to care for missing `opts['rev']`, this should be
  `opts['rev'] = ["wdir()"]`.
