What about setting comint-scroll-to-bottom-on-input to true?  ()I have that set
when I am in a shell buffer, and any keystrokes move me right to the bottom
and the prompt.)

Documentation:
Controls whether input to interpreter causes window to scroll.
If nil, then do not scroll.  If t or `all', scroll all windows showing buffer.
If `this', scroll only the selected window.

The default is nil.
