Re: Strange behaviour of auto-fill

[Christopher Dimech]

Have had another go and noticed that calling

  (turn-off-auto-fill)

will not break lines if the following is present

  (setq-default auto-fill-function 'do-auto-fill)

My impression would be for developers to take a closer look at the
code, so that it's use would be simplified.  Or perhaps some good
examples on how to use it, as it does not look so clear to me.
