    service(8): Allow for passing no arguments to the service script
    
    Currently, service(8) requires the user to provide a command to the
    rc service script. For example,
    
        service cron
    
    does not even run the cron rc service script but
    instead shows the usage message of service(8).
    
    This patch makes it so running the rc service script with no arguments
    via service(8) is closer to running the rc service script directly
    (e.g., /etc/rc.d/cron).
    
    Long story short, for most of the rc service scripts this change means
    that running "service FOO" now shows the usage message of FOO instead of
    the usage message of service(8).
