We could compare `split-window-preferred-function' with its default value
and override it in dired only when it has the default value.

Otherwise we could define a new option `dired-split-window-preferred-function'.

Do you mean `split-window-preferred-window' as a user-defined value
that replaces the `window' argument of `split-window-preferred-function'?
