24.3.50; Attributes aren't inherited in a copied face across frames |

(This happens in not only 24.3.50 but also at least 24.2.)
Say copy the built-in face `bold' to `my-bold' as follows:
(copy-face 'bold 'my-bold)
= my-bold
(face-attribute 'my-bold :weight)
=> bold
That is normal. However, if `(face-attribute ...)' is done again
in a newly created frame (by `C-x 5 2'), it returns `unspecified',
i.e., that is not a bold face in the new frame. I've tested it in
only Cygwin Emacs, sorry.

Ok. Though I cannot imagine using such a strange function usefully.

I've been using it conveniently since the face feature was introduced
in Emacs. For example, it's handy when I want a face of which only
the color differs from the built-in one:
(copy-face 'bold 'orange-bold)
(set-face-foreground 'orange-bold "Orange")
Of course doing it by defface is not so troublesome, so I can live
without copy-face.

Oh, I didn't notice the docstring having changed recently. I must
close this thread. Thanks anyway.
