FIX bug that preproc lines were getting \\ appended but not removed: do not append \\ to preproc lines.  An alternative fix would have been to remove them from preproc lines.  (Although that still won't allow indented preproc, because \\ prevents semicolon injection, it does not prevent curling on indent.)  TODO: The behaviour should of course be made optional.
