Yes, although I'm still not sure this follows the principle of least astonishment:
If no matches results in "", and the result is the sum of the matches, wouldn't you expect the result in this case to be ""+4+7, i.e. the string "47"? If an arithmetic sum is expected then you should get 0 from a non-match IMO...
