Here's another example of a limit case:

(string-match "a*" "b") returns 0, because a* matches zero or more a's,
and there are zero a's at position 0.


Hmm, interesting

IMHO that differs:

(string-match "a*" "b") asks for a non-occurrence too. So "0" of first position is plausible.


Aren't the regular expressions "" and "a*" equivalent in that respect that they both also match the empty string?
