It's a safer change.  Callers can use pop-to-buffer-same-window if they
like that better.  In the absence of display-buffer-alist there's also
a difference of behavior for softly-dedicated windows where
set-window-buffer will undedicate the window whereas
pop-to-buffer-same-window will use another window.
