Martin, when might pop-to-buffer-same-window show the buffer in a
window other than the selected one?  If we are going to make this
change, we need first to understand when it might misfire, because
some users of find-file might not like the situation where the buffer
pops up in another window.

E.g., what happens in this particular use case if the Dire4d buffer
pops in another window?
