        option to no longer imply the "path" argument.
      * Fixed insufficient buffer size used for network interface name printing,
        that previously led to assertions on attempts of printing interface names
        that require quoting, for example, names longer than 4 characters in -xx
        mode (addresses RHBZ bug #2028146).
