Hmm. Why only the former? Supporting it for the latter should be easy. (Though it would take some extra work, I guess.)

Other than that, it looks good to me.

Long line.

Should be a simple matter of

  if patch.startswith('{base}'):
      foo = repository.get_stack(branch).base + drop_prefix(patch, '{base}')
      return repository.rev_parse(foo)

or something.
