For a while now, I've been using the following customization to
display a green circle for an unmodified file and an orange square for
a modified one (versus the repository, I mean):

(setq-default
 mode-line-format
 '(...
   (vc-mode (:eval (vc-icon)))
   ...)

;; Display a coloured square indicating the vc status of the current file
(defun vc-icon ()
  (let ((icon (if (vc-workfile-unchanged-p (buffer-file-name))
                  "in-vc.png"
                "modified-vc.png"))
        (bg (face-attribute 'mode-line :background)))
    (propertize
     "  "
     'display (find-image
               `((:type png :file ,icon :ascent center :background ,bg))))))

It relies on the attached two PNG images (I presume sending
attachments to this mailing list works; if not, email me and I'll
place them on imgur or somewhere similar).
