;;; Commentary:
;; `acdw-modeline' is a dumping ground for extra modeline functions, so they
;; don't clutter up `init.el'.

;;; Code:

(require 'simple-modeline)
(require 'minions)

;; modified from `simple-modeline'
(defun acdw-modeline/modified ()

indicator in the mode-line."

	      (let* ((read-only (and buffer-read-only (buffer-file-name)))
		     (modified (buffer-modified-p)))
		(propertize
		 (if read-only " =" (if modified " +" " -"))
		 'help-echo (format
			     (concat "Buffer is %s and %smodified\n"
				     "mouse-1: Toggle read-only status.")
			     (if read-only "read-only" "writable")
			     (if modified "" "not "))
