Also note that in
       int regexec(const regex_t *restrict preg, const char *restrict string,
                   size_t nmatch, regmatch_t pmatch[restrict .nmatch],
                   int eflags);
pmatch is [1] if nmatch is 0 if eflags&REG_STARTEND.
Or, more succinctly,
  regmatch_t pmatch[restrict !!(.eflags & &REG_STARTEND) ?: .nmatch],

Doesn't really matter, and that's a much worse signature than what's
currently there, but.
