Gnus Article line wrapping

Gnus Article line wrapping

[Guillaume Riviere]

Hi,

First, after many mounth using other Mail/News reader (mozilla,
thunderbird, evolution) I come back to
Gnus, This is for me the best News/Mail reader !

My configuration is now ok, I have just a little problem with 
Gnus Article:  I search a way to automaticaly wrap lines in 
article display:

currently in the Article buffer when a ligne go outside the
gnus article size, emacs display on the rigth a "mouse clic-able"
arrows to show the rest of the line.

I search for the Key to automaticaly display a carriage return instead
of the arrow 

I also search for the add-hook method to automaticaly display article
with this "carriage return display"

In my .gnus file there is the lignes:

;; auto-fill-mode  for message 
(add-hook 'message-mode-hook 'turn-on-auto-fill)
(add-hook 'gnus-article-mode-hook 'turn-on-auto-fill)
;; truncate-lines while reading article
(add-hook 'gnus-article-mode-hook (lambda () (setq truncate-lines nil)))
(add-hook 'gnus-article-mode-hook
           '(lambda () (auto-fill-mode 1)))

But it does not work

thank in advance for help,
Guillaume
