Easy customisation.  Cool.

In it correct to use "face inferior-vshift display" in the code below?

(defun subinf-font-lock (pos)
  (unless (or (memq (get-text-property pos 'face)
                    '(font-lock-constant-face font-lock-builtin-face
                      font-lock-comment-face))
              ;; Check for backslash quoting
              (let ((odd nil)
                    (pos pos))
                (while (eq (char-before pos) ?\\)
                  (setq pos (1- pos) odd (not odd)))
                odd))
    (if (eq (char-after pos) ?_)
        `(face inferior-vshift display (raise ,(car subinf-vshift)))
      `(face superior-vshift display (raise ,(cadr subinf-vshift))))))
