[OS X Emacs] How to overwrite global line-wrapping setting for a specific mode?

[Marius Hofert]

Dear Piet,

I've already checked the other places and thought I had not changed anything else.
I did a fresh reinstall and had the same problem again. 

I finally found out that I used:
(add-hook 'ess-mode-hook
          (lambda ()
	    ... other settings for ess-mode
            (set-truncate-lines)
	    )
	  )
instead of:
(add-hook 'ess-mode-hook 'set-truncate-lines)

I thought I can just put in the additional setting concerning ess-mode in this "group of settings", but apparently not. Putting it in an extra line solved the issue.

Cheers,

Marius
