Duncan P. N. Exon Smith e784f5770f re.results.form: Format out-of-range subexpression references as null ...

Rather than crashing in match_results::format() when a reference to a
marked subexpression is out of range, format the subexpression as empty
(i.e., replace it with an empty string).  Note that
match_results::operator[]() has a range-check and returns a null match
in this case, so this just re-uses that logic.
