If you want that, just set scroll-preserve-screen-position accordingly. Maybe we should change this default value. I'd suggest you bring it up on emacs-devel to see what other people think about it. I think there's a remaining bug in that the scroll commands will use their own "temporary goal-column". So, for example, if you're on column 70, then do C-n to an empty line and then do page-down you'll end up in column 0 because page-down did not pay attention to temporary-goal-column (and vice-versa when switching from scrolling to C-n/C-p). Patch welcome to fix this as well. Stefan
