I was thinking grep. Awk or sed may be enough to generate Lisp lists, I dunno.

btw if anyone's thinking of actually implementing this Gnu grep 2.5.4 is extremely slow with some locales, awk and sed are literally hundreds of times faster. If you want to use grep set the environment variable LC_ALL=C or some such.
