A branch from a sub-directory?

That's what I was afraid would happen.  Mmaybe those "parent revision
pointers" should be marked "weak", so they can be turned into ghosts
when cloning?
[ I doubt you have such a notion of "weakness", but maybe the
  stacked-branches code uses some related functionality that could be
  abused here? ]
