Re: writing a minor mode

[Marcelo Toledo <marcelo@marcelotoledo.org>]

Isn't better just to use:

,----[ C-h f auto-fill-mode RET ]
| auto-fill-mode is an interactive compiled Lisp function in `simple'.
| (auto-fill-mode &optional ARG)
| 
| Toggle Auto Fill mode.
| With arg, turn Auto Fill mode on if and only if arg is positive.
| In Auto Fill mode, inserting a space at a column beyond
| `current-fill-column'
| automatically breaks the line at a previous space.
| 
| The value of `normal-auto-fill-function'specifies the function to use
| for àuto-fill-function'when turning Auto Fill mode on.
