This seems hardly practical. What would happen when the window must be
scrolled to bring `point' back to it? How would you show a buffer
containing such a specification in two windows?
You should be able to visualize the effect by putting a marker on that
text and adding a `recenter' call with `point' temporarily set to that
marker in your `post-command-hook'.
