As far as I can tell, the `window-scroll-functions` hook is NOT triggered when `point` STAYS between *old* `window-start` and *old* `window-end`. So when `point` STAYS between *old* `window-start` and *old* `window-end`, I will need to use the `post-command-hook`. When point moves BEYOND *old* `window-start` or `*old* `window-end`, then the `window-scroll-functions` hook can take over -- with a forced new `(window-end nil t)`. Why do you care about the situation where point stays inside the same window limits?
