    The basic idea is to allow using a lisp vector ([...]) as a kind of `or'
    expression in the attribute part of a defface clause.

Your proposal makes a number of other changes;
is this the best way to do all of them?

I don't see how an "or" construct would be a kind of clause:

      CLAUSE    ::= ATTRIBUTE
		  | (TESTS CLAUSE...)               ; traditional top-level style
		  | [SPECS ...]                     ; `or' vector style

Shouldn't it be a kind of TEST instead?
