Same 'face' spec initialized to different values for x and terminal

[Leo]

Hi Emacs developers,

The following 'face' is extracted from 'dictem.el¹'

(defface dictem-database-description-face
  '((((background light)) (:bold t :foreground "darkblue"))
    (((background dark))  (:bold t :foreground "white")))

  "The face that is used for displaying a database description"
  :group 'dictem-faces)

In X, start 'emacs -q -l dictem.el':

dictem-database-description-face is initialized to:
               ......
        Weight: bold
         Slant: unspecified
    Foreground: darkblue
               ......

In Xterm, start 'emacs -nw -q -l dictem.el':
               ......
        Weight: bold
         Slant: unspecified
    Foreground: white
               ......

*NB*: emacs has a light background in both x and xterm. Thus it looks
 very weird the aforementioned face is initialized to the dark
 background value.

Tested in GNU Emacs 23.0.0.6 (i686-pc-linux-gnu, X toolkit) of
2007-05-31.
