There are many ways to handle the problems cited (and also that of
formatting man buffers).  Basically, we should either know the size of
the window before rendering the buffer or know the rendering of the
buffer before creating the window.  I'm afraid though that any of these
approaches will require rewriting lots of `with-output-to-temp-buffer'
and similar functions.
