This probably won't help in this case, but I use ack [1] to search
source. It's smarter than grep, it knows not to look at VC files or
directories, object files, etc. Its written in standalone perl [2], so
you can just drop it in your ~/bin. Your pattern can use all of PCRE,
and it knows all about lots of different file types, eg "ack --hh"
will just search headers.

It won't help in this case though, since it doesn't know how to look
inside gzipped files.

Cheers
