Code review comment for lp:~sforshee/powerd/clean-up-cli-output

Looks cleaner, to reiterate what I said on IRC, I had someone look for "We Get Signal" when a MMS was sent, he didn't see it. When MMS does work, we may need to bring that back because it might be a different signal. tl;dr: We need to test screen on with MMS once it works.
