Adjust semantics of non-greedy operator R%S, to avoid the broken
case whereby R%S matches nothing at all when S is not empty
but equivalent to empty, or more generally when S is nullable.
A much nicer definition is ``the intersection of R* and
the set of all strings that do not contain a non-empty substring
that matches S, followed by S''.
