I have done the best I can. I do not know what to do.
The basic assumption that clip_changed can be set in narrow_to_region
etc and that redisplay later can decide when it can be reset is false.
Redisplay does not have the necessary information since it does not
know exactly why clip_changed was set to 1.
I have said that there is no reason to let narrow_to_region set
clip_changed (even if it really seems intuitively right to do so). It
is much easier to let redisplay do that instead in
reconsider_clip_changes because then all needed information for the
specific window is available.
Is this clear?
