Subject: (three_to_one_table): Don't define in UTF2000.
X-Git-Tag: r21-2-15-buf-utf8-1~10
X-Git-Url: http://git.chise.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=efdc0ab04f41b760885c9736d796a1bc2c2bb458;p=chise%2Fxemacs-chise.git-

(three_to_one_table): Don't define in UTF2000.
(bufpos_to_bytind_func): Use `buf->text->mule_size' instead of
`buf->text->mule_shifter' and `buf->text->mule_three_p' in UTF2000.
(bytind_to_bufpos_func): Likewise.
(buffer_mule_signal_inserted_region): Likewise.
(vars_of_insdel): Don't initialize `three_to_one_table'.
(init_buffer_text): Use `buf->text->mule_size' instead of
`buf->text->mule_shifter' and `buf->text->mule_three_p' in UTF2000.
