I'd like the Buffer List to always appear as a horizontal window at the
bottom.  But when I have emacs maximized and show the Buffer List, it
appears in a new window, split vertically on the right side.  I think emacs
is trying to be smart about where I've got the most screen real estate at
the moment but I wish it would always go on the bottom.  Is there a variable
to set this by chance?
