Re: Info-validate bug.

[Richard Stallman]

    To retain compatibility with all Emacs packages that you may be unaware of,
    and that use the function `Info-following-node-name', you can restore this
    function in the info.el with a new implementation:

    (defun Info-following-node-name ()
      (and (looking-at (Info-following-node-name-re))
           (match-string 1)))

That seems like a good idea, given that the function was being used
outside Info.
