status cleanup

[Wesley Shields]

A co-worker noticed that the pf rc script has 'status' listed twice when
run without any arguments. The attached patch fixes that and two other
cases where this also happens. I've only tested the pf changes. I'd
appreciate a review of this and maybe a commit? I can file a PR if it
would make people feel better.

I'm not subscribed to this list so I would appreciate being CC'ed on any
replies.
