Subject: (Q_identical): New variable.
X-Git-Tag: r21-4-14-chise-0_21-25-ii-identical^2~53
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=d46b37876ed8bf2736e4ff6fc29f4b5b397aead4;p=chise%2Fxemacs-chise.git.1

(Q_identical): New variable.
(Q_identical_from): New variable.
(Fchar_feature): Regard `->identical' as a feature to find ancestors.
(Fput_char_attribute): Add reversed link for `{->|<-}identical'.
(Fsave_char_attribute_table): Use `Fchar_refs_simplify_char_specs' for
`{->|<-}identical'.
(syms_of_chartab): Add new symbols `{->|<-}identical'.
