The problem I tried to solve was the one you reported at the beginning
of this thread: evaluate this:

    (setq scroll-preserve-screen-position 'always
          scroll-conservatively           most-positive-fixnum
          scroll-step                     0)

and then visit window.c and press and hold the <down> arrow key.  You
said that sometimes you see display being recentered, i.e. you see the
cursor near the middle of the window, instead of it being at the last
screen line.

David Engster reported the same symptoms with the above settings.
(David also used redisplay-dont-pause set to t, but I don't see
recentering with that customization, either, when I use the current
trunk.)

I would like you to try the above recipe in "emacs -Q", and tell me if
you still see recentering.

TIA
