It's simpler than that: tr(1) deletes ALL nulls, regardless of your
command line arguments.  So, to use this undocumented feature:

    setenv CLEAR "`clear | tr`"

Simple, eh?

Disclaimer: I've given up my csh(1) guru card about six months ago
(about the same time I gave up my vi(1) guru card and went to GNU
Emacs).  'setenv' syntax should thus be checked carefully; use at your
own risk. :-) (However, the trick about tr should allow me to renew my
UN*X Guru Card, eh guys?)
