bug#15714: 24.3.50; Confusing documentation of face attributes

[Xue Fuqiao]

(face-all-attributes 'default)
  =>
((:family . unspecified) (:foundry . unspecified) (:width .
specified) (:height . unspecified) (:weight . unspecified) (:slant .
specified) (:underline . unspecified) (:overline . unspecified)
strike-through . unspecified) (:box . unspecified) (:inverse-video .
specified) (:foreground . unspecified) ...)

But in (info "(elisp) Face Attributes"):

  An ‘unspecified’ attribute tells Emacs to refer instead to a parent
  face; or, failing that, to an underlying face.  The ‘default’ face
  must specify all attributes.

Unexpectedly, all the attributes returned by face-all-attributes are
‘unspecified’, so it may be a documentation bug.
