;; We used to call set-face-attribute with a nil argument here,
;; but this does the wrong thing (Bug#2476). The reason is
;; subtle: when Emacs looks for a font matching the `font'
;; argument, it tries to guess the best matching font by
;; examining the other face attributes. The attributes for
;; future frames are generally unspecified, so this matching
;; process works poorly. What we do instead is assign `font' to
;; the selected frame, then use that font object and assign it
;; to all other frames (and to future frames).
