BTW, the default-FOO vars were only deprecated in Emacs-23, not
Emacs-22, so maybe they can wait a little longer.  Actually I think most
of them can be safely dropped (e.g. because they've never been used),
but some have been used fairly commonly and should stick around a bit
longer.  Most obvious ones: default-major-mode and default-tab-width.

AFAIK buffer_defaults is indeed still very much needed for
(default-value major-mode), (setq-default major-mode ...) and same for
all other variables which have their own field in the struct buffer.

OTOH, once all the DEFVAR_BUFFER_DEFAULTS are removed, we can remove the
hack in store_symval_forwarding.
