X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=c2c3114961802b4c52b4cde0271e460fb08698cf;p=emacs.git

(SETUP_SYNTAX_TABLE_FOR_OBJECT): Take a byteoffset

* src/syntax.c (SETUP_SYNTAX_TABLE_FOR_OBJECT): Take a byteoffset.
* src/regex-emacs.c (re_search_2, re_match_2): Simplify accordingly.
