s-match: support optional capture groups
The values of match-data do not seem to support the ideal case. For the
test of "(abc)(def)?" matching against "abc", the most reasonable result
would be ("abc" "abc" nil); however, match-data provides no indication
of the second capture group.
Without this, though, s-match errors when match-data contains nils.
