Oh, and a big problem is that the "dir" file is written into the wrong
directory.  It has to be located in the root directory of the package,
not in docs/ (in the case of org-transclusion).  Sadly adjusting the
second argument doesn't fix the issue:

diff --git a/lisp/emacs-lisp/package-vc.el b/lisp/emacs-lisp/package-vc.el

                  output (buffer-name)))
        ((kill-buffer))))

While the entry does appear in (dir) Top, the file cannot be opened:

  Info-find-file: Info file ‘org-transclusion’ does not exist; consider 
installing it
