Do this and indentation will be in whitespaces only:
(setq-default indent-tabs-mode nil)
Only in Makefiles you still get tabs - otherwise they
(the Makefiles) won't work.
But to answer your question, yes, you can use
`before-save-hook' and `untabify'.
If you want to add exceptions, it could look like
this:
(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'
But I think it is better to have the file as you edit
it be as close to the finished form as possible, and
not have it post-processed like that.
