need a way to override defface?

[Drew Adams]

`setq' will override a value already given to a variable by `defvar' or
`defcustom', but is there a way to override a face already defined by
`defface'?  Interactively, you can use `C-M-x' on another `defface' to
override the previous definition, but how can you do that programmatically
(without resorting to `eval-defun')?

If there is no good way to do this, how about adding one?

What about the set-face-* functions?

Sure. What I meant, however, was something analogous to what `setq' does for
`defvar' and `defcustom'. Something, for instance, that a user can put in
.emacs to override a predefined `defface'.

Yes, I realize that users can use Customize, but I'm thinking of something
less interactive.

As another example, I just sent a message to the list about a buff-menu.el
patch. In order for others to try it out, I need to tell people to
explicitly use `C-M-x' on a particular `defface' sexp. This is because
buff-menu.el is preloaded, it calls `defface', and the patch gives a
different definition of one of the faces. It would be simpler to give people
a snippet of code to load (not eval with `C-M-x'), to override the
predefined `defface'.

Anyone else have an idea about this?
