A patch for this is attached. It _seems_ to work ok; conceptually it
seems ok too. I have done some testing which tends to indicate that it
is right, but I'm not sure of all the implications this code has so I
don't know how to test it exhaustively. Of course, regression tests
pass, but this doesn't actually prove anything.
