This beautiful snippet of .emacs code is due to Martin Maechler:

; From Martin Maechler <maechler at stat.math.ethz.ch>:
(eval-after-load "comint" '(progn
  (setq comint-scroll-to-bottom-on-output 'others)   ; not current, dflt
is nil
  ; (setq comint-scroll-show-maximum-output t)          ; I find this
too jumpy
  (define-key comint-mode-map [up]
'comint-previous-matching-input-from-input)
  (define-key comint-mode-map [down]
'comint-next-matching-input-from-input)
  (define-key comint-mode-map "\C-a" 'comint-bol-or-process-mark) )
)

I think the first indented line does what you want.  I've commented out
the
second indented line (I don't like the jumpy effect), but you could try
it.
The remaining 3 lines do other cool stuff.
