    Actually the only cases I can vaguely remember using the
    (/ (length (match-data)) 2) idiom didn't use the whole (match-data).
    They typically used the idiom in order to know *which* subgroup matched (of
    course it only works if you craft your regexp carefully).

Can't you tell that more easily by seeing if match-beginning returns nil?
