[docs] [issue22594] Add a link to the regex module in re documentation

Marco Buttu added the comment: Looking at the regex module and documentation, it is not clear to me whether its API behaves exactly as the re API. In addition, being a third-party module, things can change in the future. To be defensive, IMO it is better to write as in the Ezio comment (in the review): "mostly compatible API". I propose a shorter patch, that adds the reference at the beginning of the page (right after the module introcution). ---------- Added file: http://bugs.python.org/file46561/regex_reference.patch _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue22594> _______________________________________
