[h-e-w] autofill question

[Underwood, Jonathan]

Hi

I'm wondering why the following code in my .emacs fails to turn off
auto-fill-mode for makefile-mode and sh-mode. I'm sure i'm missing something
obvious...

;; auto-fill
(setq-default fill-column 80)
(setq-default auto-fill-function 'do-auto-fill)
(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'sh-mode-hook 'turn-off-auto-fill)
(add-hook 'makefile-mode-hook 'turn-off-auto-fill)
