Re: winner.el vs. simple.el

[Richard Stallman]

      You can switch buffers easily with the new functions prev-buffer and
      next-buffer, bound by default to C-x <left> and C-x <right>. These keys
      were previously used by commands winner-undo and winner-redo from minor
      mode winner-mode, which have been moved to C-c <left> and C-c <right>
      respectively.

Here's a clearer way to say it:

    Convenient commands to switch buffers in a cyclic order are
    C-x <left> (prev-buffer) and C-x <right> (next-buffer).

There is no need to mention winner here, since it is rather obscure.
However, there could be another entry to describe the change in winner.
