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: http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00322.html

;;; 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

(defvar Info-current-file)

|
|
(org-add-link-type "info" 'org-info-open)
