Comment: external link in xhtml?

Analysis: Problem is linked to a bug introduced in version 6.10. This version supports some Wiki codes, including 'slash-slash', the one that produces italic. Unfortunately, pattern matching rule introduced to process this code also matches web links, which kills the links.

Root cause and solution: Pattern matching '/\/\/(.*?)\/\//is', to be changed to '/([\s\(])\/\/(.*?)\/\/(\W)/is', in line 570 of codes/codes.php
