Thanks, applied. While the use of such a password may not be that good
of an idea for most cases, it should be fine to pad that password, too.
However, some RADIUS authentication servers do not seem to even allow
an empty password regardless of the padding, so this is not really that
interoperable selection for a password, never mind the lack of security.
