I don't think there's ever been such a behavior in Emacs's defaults. But I'd welcome patches which implement that functionality (tho I don't think it should special case `self-insert-command`). Dmitry mentions: > I've always had to use a third-party mode to clean up that whitespace, such > as https://github.com/purcell/whitespace-cleanup-mode (most recently). The problem with `whitespace-cleanup-mode` is that it's global. I'd like something that only operates locally, i.e. only touches lines you've modified. Stefan
