Hmm, I spoke too soon. During installworld, z*grep commands are installed
from gnu/usr.bin/grep(as hardlinks to grep), then get overwritten by shell
scripts installed from usr.bin/gzip. This was why suddenly z*grep stopped
working for multiple files. While this option to grep can be useful in
some other cases, we'd probably better change usr.bin/gzip/Makefile so as
not to install z*grep wrappers.
