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`).

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.
