It's not being called because internal-auto-fill calls do-auto-fill
instead of funcalling auto-fill-function.  But changing it to do the
latter makes no difference, since message-do-auto-fill also calls
do-auto-fill, unless point is on a message header.  (So it's still a
mystery to me why you can't reproduce the problem...)
