As we care whether it works, we should have a test for it to alert us when we break it. I'll add one as you indicate, Stefan and you can improve it if it fails to capture the essence.

By "modify startswith" I meant the one in PyShadowstring, because it copied code from PyString that I've now changed. Ideally, it would call the one in PyString instead, or maybe both call common code. This might be easier if the shadow string it held were a PyString itself. I would feel safer trying that with a test in place.
