Re: provide an easy way to customize inherited faces

[Richard Stallman]

    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?

                           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.

    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.)
