we mostly have a consistent style on if/then & for/do in devstack, except when we don't. This attempts to build a set of rules to enforce this. Because there are times when lines are legitimately long, and there is a continuation, this starts off ignoring if and for loops with continuations. But for short versions, we should enforce this. Changes to make devstack pass are included. The fact that the cleanup patch was so small is pretty solid reason that this is actually the style we've all agreed to. Part of a git stash from hong kong that I finally cleaned up. Change-Id: I6376d7afd59cc5ebba9ed69e5ee784a3d5934a10
