Re: reducing defface redundancy

[Richard Stallman]

    So a user can just write:

        [ALTERNATIVE1 ALTERNATIVE2 ... DEFAULT]

    and the lisp code will effectively say `does the display support all
    the attributes ALTERNATIVE1?  If so, lets use that.  If not, does the
    display support all the attributes in ALTERNATIVE2?  ...' etc.

I see.  This is certainly a convenient thing to do in Lisp terms.
And this, by itself, would not pose a problem for Custom.

What does pose a problem for Custom is the nesting of constructs
that you also propose to add.
