This won't apply nicely with -p1.  Nor will it apply against
current -bk (which no longer has bcopy in it, for example).

For this kind of CodingStyle cleanup, I think it's probably not worth it.  
Unless you have other changes and fixes planned in the area.

Neither of these is CodingStyle compliant ;-)  Take a look at what
Lindent does (not perfect, but good rule of thumb).
