Maybe make sense but it doesn't work.  I tried with dired-do-compress
and many marked files.  That will first create a *Marked Files* buffer,
show that as a new bottom window, and then invoke the prompting function
like yes-or-no-p.  I.e., (minibuffer-selected-window) is the window
showing the *Marked Files* buffer, not the original dired buffer.

Bye,
