Since 'cp' and 'mv' don't have any if-then-else type of control flow
that I can think of I am having a hard time thinking up a time when
they would not do exactly what you asked them to do.  Therefore a
preview --just-print mode seems of very limited value.

The rule is that it does exactly what you tell it to do but not what
you want it to do?  :-)
