Use of && and || in sh / csh

[Bill Silvert]

I have a problem with the Unisoft 2.4 on my Wicat which does not
appear under 4.2 -- the sense of && and || are reversed when run
under csh.  For example, the command line
	test -s file && echo file is there
will print the echo line if file exists and is not empty if run under
sh, but the sense of the test is reversed and nothing is printed when
I run under csh.  Is this a unique bug in Unisoft Unix, or is there a
rationale to the difference?
