Nope, both system V and Bezerkeley versions of crypt immediately
destroy (by writing nulls over the argument) any indication of the arg
(after copying it into another internal buffer).  This way, it is
*not* visible on the command line, unless you hit it at exactly the
right spot.  So it's not too much of a security glitch.
