Two things. See the docs for fill-column:
fill-column is a variable defined in `C source code'.
Its value is 70
Automatically becomes buffer-local when set in any fashion.
This variable is safe as a file local variable if its value
satisfies the predicate `integerp'.
So, when you set the fill column from your .emacs, this setting will
not apply to other buffers. To set a global default value use
setq-default:
(setq-default fill-column 5)
Furthermore you have to make sure that auto-fill-mode is turned on,
otherwise your setting will have no effect. You usually only turn it on for
certain major modes, e.g. to turn it on for latex-mode you'd add this
to your .emacs:
(add-hook 'latex-mode-hook 'turn-on-auto-fill)
You can of course also change the setting for fill-column in a
buffer-specific hook, using setq would make sense there.
HTH,
Anselm
