Make password lookup treat /dev/null as a special case

Browse source 
I have from time to time a need of random password without
wanting to write them down (one example is mailman list creation,
that requires a password to be given to be sent to the list owner).

But using /dev/null do not return null, but the empty string, which
doesn't generate a password at all and so do not achieve my use case.
