BUG [Emacs 21.1] face property ignored on some minibuffer prompts

[Francis Litterio]

In Emacs 21.1, when reading input from the minibuffer using the
following functions, the face property on the prompt string is ignored:

  y-or-n-p
  read-char
  read-char-exclusive
  read-input
  read-key-sequence

But using the following functions, the face property is honored:

  read-from-minibuffer
  yes-or-no-p

To reproduce, evaluate these Elisp forms (assuming your highlight face
is visually different from your default face):

  ;; Prompt is not highlighted ...
  (y-or-n-p (propertize "Really? " 'face 'highlight))

  ;; Prompt is not highlighted ...
  (read-char-exclusive (propertize "Really? " 'face 'highlight))

  ;; Prompt is highlighted ...
  (yes-or-no-p (propertize "Really? " 'face 'highlight))

  ;; Prompt is highlighted ...
  (read-from-minibuffer (propertize "Really? " 'face 'highlight))
