* plugins.d/mandos-client (start_mandos_communication): Bug fix; skip
                                                        non-specified
                                                        interfaces.
  (main): Use lower_privileges() consistently.  Bug fix: Don't remove
          "none" from list of interfaces.  Make --interface=none work
          again by not bringing up interfaces specified after "none".
* plugins.d/mandos-client.xml (OPTIONS): Document new meaning of
                                         specifying --interface=none
                                         together with other
                                         interface names,
