Re: Customizing faces with `defcustom'

[Richard M. Stallman]

    There is still the last face in the group `faces' that doesn't belong to
    this group: `display-time-mail-face'.  Currently it is in two groups:
    `faces' and `display-time'.  So we could remove it from `faces'.

Yes, I think we should.

    However, there is another similar face that is used to highlight text in
    the mode line: `Buffer-menu-buffer'.  We could create a new group
    `modeline-faces' and add all modeline-related faces to this new group.
    The faces that could be added to `modeline-faces' are:

    Buffer-menu-buffer
    display-time-mail-face
    mode-line-highlight
    mode-line-inactive
    mode-line

This seems ok, but please call it mode-line-faces.
