>Description:
Currently if service(8) is given just an rc.d script name and no command after,
it prints its own usage message just as if no rc.d script were passed. This
patch changes the behavior so that when just an rc.d script name is given
service(8) runs the rc.d script without arguments which causes the rc.d script
to print its usage.

I find this behavior much more useful than having to type out the full path of
the rc.d script to get its usage message.
