I'm fond of --color option in the newer grep program :)

When we switched to libz-based gzip, we also obtained the z*grep script
in our tree, but it didn't work because our grep program was too old,
and it natively supported gzip'ped files, so simply the script wasn't
needed to be installed.  The gzip support in grep was probably FreeBSD-
local modification, so someone can merge it for the new version, too,
but until that happens, here's a small patch to re-activate the z*grep
script.  I can commit it later today, if there's no objection.
