If it can be fixed by commenting in the second line of the following
comment in `pop-to-buffer'

  ;; This should be done by `select-window' below.
  ;; (set-buffer buffer)

we have the following problem: Your `fit-frame' will work when using
`pop-to-buffer' but not when using `display-buffer'.  So maybe it's
better to do the funcall in `display-buffer-pop-up-frame' as

               (with-current-buffer buffer
                 (setq frame (funcall fun)))

Please try them both, tell me whether they work for you, and, if so,
which one you prefer.

Thanks, martin
