`with-help-window' does some things differently which I could not put
into `with-output-to-temp-buffer' due to compatibility issues.  Can't
you put `temp-buffer-browse-mode' on `temp-buffer-window-show-hook'?

The idea of `with-temp-buffer' is to create a temporary buffer where you
evaluate things and _kill_ that buffer immediately afterwards.  The idea
of `with-temp-buffer-window' is to show the buffer and keep it around at
least until you quit the window.
