What do people think? I agree, but adding such a hook would cause many gratuitous diffs, which then blur VCS history (using ‘git blame’ becomes almost useless). Instead, I’d suggest using ‘show-trailing-whitespace’. Unfortunately, that can’t be a per-file or per-directory local variable [0] so we can just kindly ask people to add it to their ‘.emacs’. :-) What do you think? Thanks, Ludo’.
