This is for applications that want to know the "usually" selected
window while the minibuffer window is selected.  It's still unclear to
me what 'minibuffer-selected-window' should really return in the first
place.  Its doc-string

  Return window selected just before minibuffer window was selected.

is misleading because, while the minibuffer is active, I always can
select a window that is not minibuf_selected_window and then select
the minibuffer window again.

The current version would be for users to evaluate right now.  If it
suits their needs, we can always provide it as a primitive.
