for gnu find, that does appear to be true. It's unfortunately not
true of all versions of find. this behaviour is new to me.

Which describes most people in this world. I for one, have no clue
what cups does under the covers with all the postscript rendering,
etc. I just knows that it listens on the lpd port and forwards things
to my jetdirect printer. It's impossible to be an expert on
everything, and I intended this (mostly xargs for performance) as an
instructional lesson for those who know less. OK, so I'm not perfect.
I've learned something new, and off I go.
