This is caused by your 2002-12-28 change to comint-mode that sets
scroll-conseratively to 10000. This was reported and diagnosed two
years ago, and you said:

    I put that in because it did not work otherwise. So I can't take
    it out. I could imagine conditionalizing that setq on some of
    those other variables, such as comint-scroll-to-bottom... That
    would not be 100% correct, since changing those variables would
    not have the right effect on an existing shell buffer. But it
    might be better than nothing.

I tried let-binding scroll-conservatively in
comint-postoutput-scroll-to-bottom, but it does not help. In other
words, things like this don't work, for reasons I don't understand:

  (setq scroll-conservatively 0)
  (let ((scroll-conservatively 10000))  ; no effect
    (goto-char (point-max)))            ; still acts like s-c = 0
