I think Lars wrote this only for performance reasons as primitive (see
the thread starting with [1]).

Otherwise, the visual effect is the same as with

(defun add-face-text-property (start end face &optional append object)
  (funcall (if append
               #'font-lock-append-text-property
             #'font-lock-prepend-text-property)
           start end 'face face object))

The functions called here seem to exist since

1995-10-26  Simon Marshall  <address@hidden>

        * font-lock.el: General reorganization.
        [...]
        (font-lock-fillin-text-property, font-lock-prepend-text-property,
        font-lock-append-text-property): New text property functions.
