"Display the warning buffer at the bottom of the screen.
The output window will be scrolled to the bottom of the buffer
to show the last warning message."
"Whether to display the warning buffer at the bottom of the screen.
If this is non-nil (the default), Emacs will attempt to display the
window showing the warning buffer at the bottom of the selected
frame, whether by reusing the bottom-most window or by creating a
new window at the bottom of the frame. The resulting window will be
scrolled to the bottom of the buffer to show the last warning message.
If the value of this variable is nil, Emacs will display the warning
buffer in some window, as determined by `display-buffer' and its
customizations. In particular, the category designated by the
symbol `warning' can be used in `display-buffer-alist' to customize
the display of this buffer."
