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 open files in doc-view-mode.
|
|
;; Org-mode loads this module by default - if this is not what you want,
|
|
;; configure the variable `org-modules'.
|
|
|
|
;; The links take the form
|
|
;;
|
|
;; docview:<file path>::<page number>
|
|
;;
|
|
;; for example: [[docview:~/.elisp/org/doc/org.pdf::1][Org-Mode Manual]]
|
|
;;
|
|
;; Autocompletion for inserting links is supported; you will be
|
|
;; prompted for a file and a page number.
|
|
;;
|
|
;; If you use org-store-link in a doc-view mode buffer, the stored
|
|
;; link will point to the current page.
