Bastien Guerry 58f1dbccf8 Remove the "Version" header in Org libraries (leave it in org.el).
Also remove blank lines before the ";;; org*el ends here" declarations.

Having a "Version" header forced us to update every file when releasing a
new version of Org; it also forced us to update every file when merging Org
with Emacs trunk, thus cluttering the diffs between the previously merged
version and the new one with useless information.

Glenn Morris suggested this in emacs-devel:

;;; Commentary:
;; This file implements links to Info nodes from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;;; Code:
(require 'org)
;; Declare external functions and variables
(declare-function Info-find-node "info" (filename nodename
&optional no-going-back))
(defvar Info-current-file)
(defvar Info-current-node)
;; Install the link type
(org-add-link-type "info" 'org-info-open)
(add-hook 'org-store-link-functions 'org-info-store-link)
;; Implementation
(defun org-info-store-link ()
"Store a link to an Info file and node."
