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

;; This accepts a 'file' header argument which is the target of the
|
|
;; compiled sass. The default output type for sass evaluation is
|
|
;; either file (if a 'file' header argument was given) or scalar if no
|
|
;; such header argument was supplied.
|
|
;;
|
|
;; A 'cmdline' header argument can be supplied to pass arguments to
|
|
;; the sass command line.
