From: Juri Linkov Date: Fri, 2 Dec 2011 10:19:49 +0000 (+0200) Subject: Change `wordify' to `word-search-regexp'. X-Git-Tag: emacs-pretest-24.0.93~232^2~37 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=02b16839f5242e93a234e7ebb0578d5aebb529ca;p=emacs.git Change `wordify' to `word-search-regexp'. * lisp/isearch.el (isearch-occur): Use `word-search-regexp' for `isearch-word'. (isearch-search-and-update): Add condition for `isearch-word' and call `word-search-regexp'. * src/search.c (Fword_search_regexp): New Lisp function created from `wordify'. Change type of arg `lax' from `int' to `Lisp_Object'. (Fword_search_backward, Fword_search_forward) (Fword_search_backward_lax, Fword_search_forward_lax): Use `Fword_search_regexp' instead of `wordify'. Doc fix. (syms_of_search): Define `Sword_search_regexp'.
