No, I was wrong: a ring isn't a good fit for the design, in which
`switch-to-prev-buffer' (i) switches to the previous buffers displayed
in the buffer, and (ii) after successive `switch-to-prev-buffer's reach
the end of that list, the command moves on to other buffers in the
buffer list which the window hadn't visited before.  If we used a ring,
we'd never hit the end, so we'd never move on to (ii).

But I think the next-buffers list should be considered an internal
detail (i.e. internal to the workings of next-buffer/previous-buffer),
and shouldn't be documented in the Lisp manual.
