-   I'd like the =C-l= to work more like the standard terminal (which works
-   like running =clear=), and resolve this by simply removing the
-   buffer-content. Mind that this is not how =clear= works, it simply adds a
-   bunch of newlines, and puts the prompt at the top of the window, so it
-   does not remove anything. In Emacs removing stuff is less of a worry,
-   since we can always undo!
