To be clear, this action came from two desires:

1. The (inhibit-same-window . t) is there to get the
dont-cover-up-control-buffer behavior

2. The display-buffer-pop-up-window action is there to handle bug 19901.
There the user already has two windows, and by default a third is
created. It's less obvious to me which is the "right" behavior here, but
the earlier behavior of reusing the window seems reasonable.
