linewrapping in emacs

[Joerg Johannes]

Hi List.

I have the following two lines in my .emacs file:

(auto-fill-mode 1)
tex-mode-hook '(lambda () (font-lock-mode 1) (auto-fill-mode 1))

But I still always have to type M-x auto-fill-mode in any mode I use to get 
linewrap. What else do I need to do?

thanks
