------- Additional Comments from Gavin Barraclough <barraclough at apple.com>
Hmmm, think I added these at an early state of development, thinking PCRE's
behaviour of coalescing results across repeated iterations of karen matching
was correct (ie. /(?:(a)|(b))/.exec(ab) as ["ab", "a", "b"], rather than 
["ab", , "b"]).  Anyway, good catch, yes, these look like garbage now.
