Attached you can find the current version of scroll-lock.el which will
keep point horizontally fixed (as far as possible) for line- and
paragraph-based scrolling.  This could be extended to page-based
scrolling (`C-v', `M-v') and be made configurable if necessary.

Compared to the last version I removed the key binding for toggling
the mode, made the mode buffer-local, and made it possible for point
to move upwards when `C-p' and similar is typed at the top of the
buffer and to move downward when `C-n' is typed at the bottom of the

Apart for the points mentioned above the file is ready for inclusion
into Emacs if people like to have it.
