`dired-pop-to-buffer' could bind `split-window-preferred-function' to a
function that tries to always split the selected window instead of
whatever window was chosen by `display-buffer' but that would override
any user customizations of `split-window-preferred-function'.

We could also provide a variable `split-window-preferred-window', nil by
default, which the window choosing mechanism of `display-buffer' would
respect if bound to some live window.  And we could turn this variable
into an option (now or later).
