Speak for your own C-shell. 

In SCO Xenix, the C-shell thinks it really is C:

	test -s /usr/spool/mail/miller 

returns 0 (assuming the file is nonempty) so the C-shell doesn't 
evaluate the second half of the conditional expression.

&& and || both work exactly the opposite of how one would expect them to 
work (and of how they do in fact work in the Bourne shell).
