If a vlan interface is a number, then that number is treated as the vlan tag for the interface and the interface will be named '.'. Otherwise, the vlan tag must be provided via a vlan parameter in a 'create_args_' variable. While I'm here, fix a few nits in rc.conf(5) and mention create_args_ in the description of cloned_interfaces.
