    So should `auto-fill-function' be a safe local variable?

In general, it cannot be safe.  Its value is a function.
But we could say that the value nil is safe for it.

Perhaps it is unfortunate that the variable which controls
Auto Fill mode has a function value rather than a boolean value.
If nobody makes use of the potential to specify different kinds of
auto-filling functions, perhaps we should replace it with a boolean
variable `auto-fill-mode'.
