I don't much care for this patch, seeing that

        find /usr/src/sys -name '*.c' -print|xargs grep '^limfree'

works just fine for me (and giving xargs top-of-mind awareness is just a
good thing anyway, IMHO).

If you want to build recursion into grep, do it right, and do it so that
you can grep recursively in just files called '*.c'.
