Re: [help-texinfo] not pointed to

[Karl Berry]

    Is it an undocumented feature or one
    documented where I didn't find it?

Nothing much has changed in the manual since 4.7 in this regard.

Various statements would imply it could be done, but I couldn't find it
documented explicitly, so I added this paragraph to the `Writing a Node'
node:

  The @var{node-name} argument must be present, but the others are
  optional.  If you wish to specify some but not others, just insert
  commas as needed, as in: @samp{@@node mynode,,,uppernode}.  However,
  we recommend leaving off all the pointers and letting @code{makeinfo}
  determine them, as described above.

Thanks,
