bug#10451: 24.0.92; Bad cross reference in Info manual

[Drew Adams]

It's the one I pretty clearly cited:

>> Please note that the links I am talking about are in node 
>> `Help Xref', not in node `Expert Info'.

And in the same mail I quoted the same text from node `Help Xref' (twice now).

Yes, I am talking about node `Help Xref'.

I addressed that in the original bug report:

And no, it is not true that "this [Info] manual also comes with the Texinfo
package".  That might be true sometimes, but it is not true in general.

That's the point.  If the `Info' manual always came with the `Texinfo' manual
then I would not have filed this bug report - the links would just work.  Please
read what I wrote.

For an Emacs distribution (this is an _Emacs_ bug report), it is not always the
case that Emacs is distributed with Texinfo (and rightly so, IMHO).

If you can find a way to make the text be such that it works for Info with
Texinfo (and perhaps without Emacs) as well as working for Info with Emacs but
without Texinfo, fine.  Barring that, let's please fix this for Emacs users -
people who will read Info within Emacs, and who will not necessarily also have
the Texinfo manual installed.
