Hi Paul,

Yes, there is a way to customize scrolling to achieve what you want.

To get the behavior you just described, you can customize or set in your
~/.emacs file `scroll-conservatively' to 1.

Note that the value of `scroll-conservatively' becomes buffer-local when
set, so it can have different values in different modes.  For example if
you want the default to be 1 for all new buffers (the behavior you just
described), but the original Emacs behavior is ok for C code, you can
use the following in your ~/.emacs file to set its value:

    (setq-default scroll-conservatively 1)
    (add-hook c-mode-common-hook
      '(lambda ()
         (setq scroll-conservatively 0)))
