Why is `indent-tabs-mode' t by default? Tabs should not
be used.

Anyway here is how I do it:

;;; -*- lexical-binding: t -*-
;;
;; this file:
;;   https://dataswamp.org/~incal/emacs-init/tabs.el

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

(setq-default tab-width 3)

(setq-default indent-tabs-mode nil)

(provide 'tabs)

And then

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