match-beginning tells: Return value is undefined if the last search failed.
Consider it a gain if it returns nil when failing.
Thanks,
Andreas

I think match-string already implicitly relies on the suggested
behaviour; compare its docstring:
Value is nil if NUMth pair didn't match, or there were less than NUM pairs.
with its implementation:
(if (match-beginning num)
(if string
(substring string (match-beginning num) (match-end num))
(buffer-substring (match-beginning num) (match-end num))))
