fix longstanding search bug involving searching for Control-1 chars -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-01-29 Ben Wing <ben@xemacs.org> * search.c (boyer_moore): Fix longstanding bug involving searching for Control-1 chars; code was trying to directly extract the last byte in the textual representation of a char from an Ichar (and doing it in a buggy fashion) rather than just converting the Ichar to text and looking at the last byte. tests/ChangeLog addition: 2010-01-29 Ben Wing <ben@xemacs.org> * automated/search-tests.el: New file. * automated/search-tests.el: * automated/case-tests.el: * automated/case-tests.el (pristine-case-table): Removed. * automated/case-tests.el (uni-mappings): * automated/lisp-tests.el: * automated/regexp-tests.el: Extract some search-related code from case-tests and regexp-tests and move to search-tests. Move some regexp-related code from lisp-tests to regexp-tests. Write a comment trying to express the proper division of labor between case-tests, search-tests and regexp-tests. Add a new test for the Control-1 search bug. Fix a buggy test in the Unicode torture-test section of case-tests.el.
