I guess it means one should use the face, not the variable.

I do this so I don't have to bother with trailing whitespace or
tabs. Maybe one can configure that in an easier way, because
it feels like a basic thing to do.

(defun untab-all ()
  (unless (member major-mode '(makefile-gmake-mode
                               makefile-mode) ) ; exceptions
    (untabify (point-min) (point-max)))
  nil) ; tell "did not write buffer to disk"

(setq-default tab-width 3)

(setq-default indent-tabs-mode nil)

;; (setq before-save-hook nil)
(defun before-save-hook-f ()
  (untab-all)
  (delete-trailing-whitespace) )
(add-hook 'before-save-hook #'before-save-hook-f)
