Subject: [PATCH] ip/routef lifesaver

keep people from screwing their systems with routef

minor patch here ... if you run `routef --help`,
it'll turn around and flush your routing tables anyways :)

so patch will have routef output usage if any arguments are given,
otherwise it'll flush the tables ... idea is from Lars Strojny
