Why doesn't do_scroll_up work the same way? There is no valid reason to scroll 
content out of the window that doesn't also apply to do_scroll_up.

The current behavior has the same visual appearance as do_cut_text_void when 
used on the first line of a file, of any size. Wouldn't it be better to have 
do_scroll_up/down move the cursor if the content can't be scrolled any further?

Doesn't emacs have a long startup time and use a lot of memory? Just because 
another editor does something doesn't mean its the correct way.
