Re: Customizing faces with `defcustom'

[Richard M. Stallman]

    Selecting a good face name will also set up a rule for naming more
    mode line faces that could be added after the release, e.g.
    (existing variable vs. new face name):

    mode-line-mule-info variable - mode-line-mule face
    mode-line-modified variable - mode-line-modified face
    mode-line-frame-identification variable - mode-line-frame face
    mode-line-position variable - mode-line-position face

It is logical, but far too complicated, and not worth it.  I would
rather have just the one face, called mode-line-emphasis or
mode-line-location or mode-line-subject-matter, and use that for the
buffer name and the info node name, and for any other similar thing.
