I'd like to see an option for preventing the cursor for moving off the end of
lines.  For this to be useful (for me), it must be implemented along the
following lines:

The cursor has two horizontal position; one displayed and one virtual.  The
virtual position is the same as the displayed position as long as the user is
typing or moving the cursor sideways.  When the user moves the cursor up or
down, the display position is clipped to stay to the left of the current line
end, but the virtual position is unchanged.

Thus, pressing down a couple of times, then up the same amount of times will
always get you back to where you started from.

If you want to see this demonstrated, this is the way Emacs implements it
(AFAICT).  If my explanation is unclear, please let me know and I'll try to clarify.
