* Allow multiple commands in $ifconfig_xxN variables in rc.conf(5).
  This may be done either by embedding newlines in the value,
  or by using semicolons to represent line breaks (but not both at once).
* Allow shell quoting insode $ifconfig_xxN variables or /etc/ifconfig.xxN
  files.  This allows something like ifconfig_wi0="ssid 'my network'; dhcp"
