? It is already the default, and it's called
`comint-scroll-show-maximum-output'.

However, we also find this comment in `comint-mode':

    ;; Following disabled because it seems to break the case when
    ;; comint-scroll-show-maximum-output is nil, and no-one can remember
    ;; what the original problem was.  If there are problems with point

    ;; This makes it really work to keep point at the bottom.

    ;; (setq scroll-conservatively 10000)
