Then this could be an easy to explain rule.  I'm only unsure about the
WINDOW argument.  What if another function has a WINDOW argument in
another position, not the first?  Maybe better to allow a lambda like this:

(pop-to-buffer (generate-new-buffer "*edit string*")
               '(display-buffer-below-selected
                 (window-height . (lambda (window)
                                    (fit-window-to-buffer window nil 10)))))
