No way .. you picked something I didn't know:

I check the manual .. yup, you can match
subgroups like that..

How does that work??? The algorithm for handling
this for a DFA is non-trivial. Any pointers to
the algorithm used?

Alain Frisch pointed me at some nasty papers on
this, one with a regexp -> NFA conversion and the
other with a NFA-> DFA conversion, but I couldn't
figure out how to do the direct regexp->DFA conversion,
I'd sure like to find an algorithm for that..
