Quantifier follows nothing in regex
This changes the code so that any '?' immediately (subject to /x rules)
following a {0} quantifier is absorbed immediately as part of that
quantifier. This allows the optimization to NOTHING to work for
non-greedy matches.
Thanks to Yves Orton for doing most of the leg work on this
