I guess we can, maybe try to replace it with "-none", as it shouldn't be
used as username anyway, because it starts with hyphen. (per POSIX)

It seems to be used as option in "aclgrp" and "password" commands and I
guess it may make more sense to start such command switch with hyphen.

Do you have time to make a patch?
