Virtually, that's what the code does.

But the buffer shown via C-x right might have been shown there for quite
some while.

I'm not sure what this means to do instead.  Have `quit-window' not show
a buffer if it appears on `window-next-buffers'?  What happens if you
turn the form

		   (or bury-or-kill (not (memq buffer next-buffers))))

in `switch-to-prev-buffer' into

		   (not (memq buffer next-buffers)))

I have no idea what else this could affect, though.
