What is the relevance of having the value cell of symbol auto-fill-mode
void? Why do you recommend auto-fill-function instead?

Looks like auto-fill-function is a variable called in auto-fill-mode.
You seem to imply that setting the variable auto-fill-function breaks
the line without needing to utilise auto-fill-mode.

Very clear, thank you.  This got us back to what Daniela was doing with
mode-line.  Quite many things can be linked together.  She has not managed
to revert mode-line to its original value, last time we talked about that.
