If we want to enable user control of displaying warnings, we will have
to add an option for that, because currently that cannot be
controlled.  display-buffer-alist is inappropriate for such control,
since in some cases warnings are not displayed in pop-up windows.

That's not TRT, because in some cases warnings are not displayed via
display-buffer.  So documenting this would produce inaccurate
documentation.

Thanks, but what do you mean by "at the bottom"?  Can you describe
that place more precisely?
