Should a `grep -r DUMMY_NOPS *' in /usr/src not have found that file,
or is `man 1 grep' just ambigous WRT to the -r option e.g. it doesn't
recurse deeper than one level?
Iff this is so, I think the manpage should be a little more explicit, so
even I can interpret it correctly. :-)
Also the behavior of grep -r is different from cd -r, and knowing cp
better I assumed grep options were nearly the same.
It's just a small thing ...
UNIX, reach out and grep someone!
