This only works when you are not already inside another repository. In
that case we infer the right repository from the filenames. This is done
by literally calling the dispatch function again with a --repository


One condition that you can read out of the code is that all files must
be inside the same repository, so

  hg log repo-a/x repo-b/y

is forbidden, of course.
