Drat! I keep forgetting that things have changed, improvements been
made,... to some of this stuff over the decades! I skipped right over
the "--null" in cpio. Thanks for reminding me to... "man xyz" even old
friends!

He'd have been OK if grep could have done the same for him, I guess.

Hmm... in line with my new found policy of "man old_friends", grep came
close, but "no cigar" with the "-Z/--null" param. However, if the "-a/--
text" param is added, it seems to do OK.

Why do the GNUrus keep fixing things that aren't broken! I know in this
environ, a series (pipeline) of modules that "do one thing and do it
well" is not as good as a single command to "do all things and none
well".
