Re: pxref

[Richard M. Stallman]

    However, I think a cross-reference in parens which is a complete
    sentence is a very rare situation.  I found only 45 such cases in all
    the Emacs manuals (in man/, lispref/ and lispintro/), and only 11 in
    the Texinfo manual.  Almost all of these look like a @pxref in
    disguise, as the sentence in parens is very short, mostly just the
    @xref itself.

    So I think it is safe for us to hide the period in this case.

I have no particular opinion about it.
