I've now fixed this in a different manner.  Your patch would have bugged
out if the empty anchor was the first element in the buffer, so I just
made it insert a "*" if we have an empty anchor.

The anchoring mechanism should perhaps be implemented in a different
way -- markers instead of text properties, for instance?  That way
zero-length anchors would be no problem.  Rewriting it in that way
should probably wait until after the feature freeze, though.
