Fixes a bug introduced with r1574404 (forgot that shutdown and status historicaly have a prefixing dash), thanks to Youseek Khaye who spotted it and sent me a mail (the stop target was no longer working). I tested them only with a portoffset, my bad.

While working on this I spotted another error introduced earlier with r1533839. Now, status and stop work again as before.
