Re: pxref

[Richard M. Stallman]

    The Texinfo source produces this in the Info output format.  (This
    output is not indented four spaces; I did that for this message.)

        Here is an @xref as a sentence.  *Note Musings on fossil fuels::.

        Here is an @ref in a sentence, see *Note Musings on fossil fuels::.

        Here is an @pxref parenthetically (*Note Musings on fossil fuels::)
         in a sentence.

    Note the `see' from the source for the @ref and the one space
    indentation of the `in' for the @pxref.

That last seems to be a bug in Texinfo.  Why does it indent that space?

      (Perhaps the source should
    not be written with `see'.  I have left it because many make this
    mistake although the Texinfo manual counsels against it.)

It is correct to write "see" before @ref; that is necessary to get
the right output in DVI.

This change in Emacs should prevent Emacs from displaying a second "see".
Does it work right for you?
