It _is_ new.  But I also don't understand why Nick thinks he needs
Texinfo 6.8.  AFAIR, makeinfo supported @node lines without explicit
pointers since at least version 4.8.  I have on my disk the manual
produced for Emacs 22.1, where the Texinfo sources have no pointers,
e.g.:

  @node Abbrev Concepts

and the corresponding Info file says:

  This is ../info/emacs, produced by makeinfo version 4.8 from emacs.texi.

So I'm not sure what exactly is the feature that requires Texinfo 6.8.
What am I missing?
