Nice one. I have a perl script for the same purpose...

#!/usr/bin/perl -w
use strict;

my $grepfiles = join(' ', split(/\n/, `ls src/*/*.[ch] include/*.h 
include/*/*.h src/gmxlib/nonbonded/nb_kernel*/*.[ch] 

foreach my $text ( @ARGV ) {
     print `grep '$text' $grepfiles`;

Your "find" idiom is more elegant. My approach allows for multiple 
search keys supplied on the command line. If I ever encountered a more 
complex need, I'd make it handle regexps too!
