Re: Changes to windows.texi

[Richard M. Stallman]

    This usage of @xref in the middle of a sentence produces badly
    capitalized English, because @xref generates "See ..." with a capital
    S.  The right way of writing this kind of text is either

      The selected window's buffer is usually the current buffer (except
      when @code{set-buffer} has been used), see @ref{Current Buffer}.

It isn't correct to use a comma there -- you need a semicolon.

      If @var{window} is omitted, this function returns the buffer for the
      selected window.

Better is "If you omit..." since it is the active voice.
