User's point of view will not be served if we distort the reality
while presenting it to the user.  The notion of point and its movement
is central to understanding Emacs, and realizing that changes like
point motion come first, while display of the cursor comes later, is
important to being able to extend Emacs and write Emacs Lisp programs.
