You are supposed to use (add-hook 'text-mode-hook 'turn-on-auto-fill) instead of your setq statement. The reason is that a hook is normally a list of functions to run. But if you use the setq statement, then the hook will be just a single function, with no way to put in multiple functions. What if you also want to use abbreviations in text mode? Then you need abbrev-mode in the text-mode-hook, too, and your setq will break. Once upon a time, having a hook be a single function rather than a list of functions was supported, but now I think it does not make sense to cater for that use anymore. Kai
