how does it compare to:
	find /usr/src/sys -name "*.c" | xargs grep '^limfree' /dev/null
?

i think i'd best describe a patch that does that as ...
architecturally challenged, and not just a bit against the spirit of
what grep is 'supposed' to do.

the find ... | xargs ... is:
	(1) probably not that much more inefficient,
	(2) is portable to any POSIX system,
	(3) is more flexible (both because of find's flexibility, and
	    because you can do a lot with a pipeline).

why build unnecessary (and, in my opinion, dumb) functionality into
grep?
