To define such a mode, we'll need to know when to enable it and when
not: I'd be surprised if adding `delete-trailing-whitespace` globally
to `before-save-hook` doesn't cause problems in various circumstances.

I don't have enough experience with that, so I'll let others decide if
and how to do it.
