[Powertop] [PATCH] Fixes to manpage and command line handling

Hello, I just decided to play with powertop again. So git pull, find out the repo has moved etcetc. I found a few cosmetic things within the first 5 minutes of use which I decided to provide a fix for. Please apply if it is acceptable, otherwise let me know how to improve it. Thanks Jörg -- Joerg Mayer <jmayer(a)loplof.de&gt; We are stuck with technology when what we really want is just stuff that works. Some say that should read Microsoft instead of technology.
