hehe, eh, thanks i suppose.  Its covered in Chapter 6.  It's a use of
what Friedl calls "Unrolling-the-Loop" for regexes.  It's one of the
coolest regex optimizations ever deviced in my opinion.

P.S.
Sorry for not being able to explain why (or more interestingly how) in
more detail, but Friedl spends some 60-70 pages on this, so it wouldn't
really be possible.
D.S.
