RE: provide an easy way to customize inherited faces

[Drew Adams]

        In Customize, when a face inherits from another, only the
        directly inherited face name appears, and it appears only as
        text in an editable field. If you know what you're doing, then
        you can put point in the field and use M-x
        customize-face. Even then, however, the default value is
        just the face name in the editable field;

    What else would it be?

I meant that you see only the directly inherited face name there. You cannot
see faces inherited from that face.

Also, as Stefan pointed out, what happens if a face inherits from more than
one face - which is used as the editable text? I haven't experimented with
this - are there a series of editable fields, one for each inherited face?

          there is no easy way to customize other faces in the
        inheritance hierarchy.

    This doesn't seem wrong, really.  If you customize the other face,
    that will show you whatever face it inherits from, etc.

Yes, but that is more roundabout than necessary. Most inheritance
hierarchies will be pretty shallow. Why not show all the faces that are
inherited?

        When a face inherits from others, the list of inherited
        faces should be shown explicitly in the Customize buffer in
        some fashion. A simple list next to the editable field
        (perhaps with items separated by  "<"), would suffice.

    If someone wants to do it, it can't hurt.
    (We don't want to install it now, of course.)

Agreed - no need to do it now.
