Ah, now I'm beginning to see your point.  I would have _sworn_ that 
"| xargs <cmd>" did not take the max # arguments into account, which is
why I thought '-0' somehow altered that.
But I am clearly wrong - "| xargs <cmd>" _does_ know about max number of
arguments.

I still feel certain I've done stuff like:

find <dir> -type f | xargs zgrep -i blah

and seen something like "too many arguments" or whatever it is, but of
course I can't reproduce that now.

It's not as if I haven't been using xargs, I think I use it quite a few
times daily - but as Peter Zeljkovic said "You learn something new
every day".
