Sounds good to me.  What do you think would be better, to supplement
widen-automatically with widen-to-pos-function, or remove
widen-automatically and only offer widen-to-pos-function?  From a
user's perspective, it might be useful to keep both around (allowing
widen-automatically to easily be set to nil in some buffers where it's
unwanted).
