It is very easy to add a customizable variable to the Lisp version,
as you already did in your patch.

Placement can be changed in Lisp by redefining the function
`minibuf-depth-setup-minibuffer'.  And I can do this because I prefer
putting this indicator to the end of the prompt by using after-string
instead of before-string.

Please note that the C version uses the same method of putting the overlay
with the formatted indicator to the minibuffer prompt as the Lisp version.
And if it interacts badly with your other eight minibuffer setup hooks,
you are unable to fix this conflict with the hard-coded C version.
