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

[Marius Hofert]

I really don't get this. I removed everything from Preferences.el and put in:

(setq-default truncate-lines t)

This should set the default to truncated lines (which is more than what I want, but let's do this for the moment). When I close and reopen Aquamacs, I still get the file(s) in word-wrap. So apparently, my settings in Preferences.el are ignored. I also tried "(set-default 'truncate-lines t)". Again, files are opened in word wrap.

Cheers,

Marius
