Time travel...2006...

https://www.emacswiki.org/emacs/download/mb-depth%2b.el

And here's (all of) the code:

(defface minibuffer-depth-indicator '((t (:inherit default)))
  "Face used to indicate minibuffer depth."
  :group 'convenience :group 'faces)

(defcustom minibuffer-depth-indicator-format "%d) "
  "Format string for minibuffer depth indicator."
  :type 'string :group 'convenience)


;; REPLACE original defined in `mb-depth.el'.
;; Use face `minibuffer-depth-indicator' and option
;; `minibuffer-depth-indicator-format'.
;;
;; This function goes on `minibuffer-setup-hook'.
;;
(defun minibuffer-depth-setup ()
  "Set up a minibuffer for `minibuffer-depth-indicate-mode'.
The prompt should already have been inserted."
  (when (> (minibuffer-depth) 1)
    (setq minibuffer-depth-overlay
          (make-overlay (point-min) (1+ (point-min))))
    (overlay-put minibuffer-depth-overlay 'before-string
                 (if minibuffer-depth-indicator-function
                     (funcall minibuffer-depth-indicator-function
                              (minibuffer-depth))
                   (propertize
                    (format minibuffer-depth-indicator-format
                            (minibuffer-depth))
                    'face 'minibuffer-depth-indicator)))
    (overlay-put minibuffer-depth-overlay 'evaporate t)))
