> Hello, Emacs.
>
> On master, when a face is set up for a single type of terminal, or
> several types of terminal, customize-face disregards this, and
> obliterates all members of the "face spec" alist except one, which is
> always t.
>
> For example, suppose we have either of these in a custom-set-faces list:
>
> '(font-lock-function-name-face ((((background dark)) (:foreground "cyan" 
> :weight bold))
>                                  (t (:foreground "Blue1" :weight bold))))
>  
> '(font-lock-function-name-face ((((background dark)) (:foreground "cyan" 
> :weight bold))))
>
> .  In a light backgrounded Emacs session (e.g. in X-Windows) run
> customize-face on font-lock-function-name-face.  Make some change to the
> face and click on <apply and save>.  The (background dark) element has
> now been obliterated, leaving (in either case):
>
> '(font-lock-function-name-face ((t (:foreground "Blue1" :weight bold))))
>
> .  This is a bug.  customize-face should respect face settings which are
> inapplicable on the current terminal.
