This means disabling RET on links in etc/TODO and all other
link-rich files that use 'view-help-file':

(defun describe-distribution ()
  "Display info on how to obtain the latest version of GNU Emacs."
  (interactive)
  (view-help-file "DISTRIB"))

(defun describe-copying ()
  "Display info on how you may redistribute copies of GNU Emacs."
  (interactive)
  (view-help-file "COPYING"))

(defun view-emacs-problems ()
  "Display info on known problems with Emacs and possible workarounds."
  (interactive)
  (view-help-file "PROBLEMS"))

(defun view-emacs-debugging ()
  "Display info on how to debug Emacs problems."
  (interactive)
  (view-help-file "DEBUG"))

For a long time I had been using RET to scroll by one line in Info:

  (define-key Info-mode-map [return]
    (lambda ()
      (interactive)
      (if nil ;; TODO: add predicate to check if point is on Info refs
          (Info-follow-nearest-node)
        (View-scroll-line-forward))))

But still can't find a predicate that would prevent RET from visiting
a reference only when the cursor moves to it while scrolling.
And don't believe this is possible.  So need to use other
less intuitive keys to visit links.
