For certain patterns, re-matching the same regexp on the matched substring does not produce correctly translated match data (bug#15107 and bug#44861). Using a new builtin function also improves performance since the number of calls to string-match is halved. Reported by Kevin Ryde and Shigeru Fukaya. * lisp/subr.el (replace-regexp-in-string): Translate the match data using match-data--translate instead of trusting a call to string-match on the matched string to do the job. * test/lisp/subr-tests.el (subr-replace-regexp-in-string): Add test cases. * src/search.c (Fmatch_data__translate): New internal function. (syms_of_search): Register it as a subroutine.
