Obviously.  Do we want to control filling via `display-buffer'?

Anyway, the output happens via `with-output-to-temp-buffer' which has no
direct means to pass an appropriate action to `display-buffer'.  If we
used `with-temp-buffer-window' instead, we could pass an ACTION argument
to fill the buffer according to the size of the window used instead of
adjusting the window to the buffer size.  In that case the configuration
could be controlled via `display-buffer-alist'.
