Michael Scherer 6fae1d2bbf Make password lookup treat /dev/null as a special case ... 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.		2017-02-15 12:15:09 -08:00
