Can you clear up a mystery about it? From looking at the code, it looks 
as though it can do lazy matching (references to REnmq, "minimal munch", 
and parsing of *?, +?, etc), and it's passed the simple tests I've tried 
on it. But it's not documented! So is the lazy matching:
(a) working, but not documented, or
(b) unfinished and buggy?
