ack now runs on a standard Perl 5.8.8 install with no module updates.
Thanks, Michael McClimon.

ack was colorizing captured groups even if --nocolor was given.
Thanks, Dale Sedivic.

[OPTIMIZATIONS]
It turns out that ack 2 is a good deal slower than ack 1.96.  We have made
a number of speedups but we are not yet at ack 1.x performance levels.
You probably won't notice any differences unless you're working with very
large code repositories, so please don't let this scare you from ack 2.

Removed a use of $& that slowed down grouped matches.  Thanks,
Michael McClimon.
