23587,url_to_postid() needs to use # or @ for preg_match start/end character,coreygilmore,,"[source:/tags/3.5.1/wp-includes/rewrite.php@23479#L344 url_to_postid()] uses ! for the start/end characters of regular expressions, which doesn't allow you to use expressions containing `!`, like `(?!negativelookahead)`.

The solution is to use `preg_match(""#^$match#"", $request_match, $matches)` or `preg_match(""@^$match@"", $request_match, $matches)`
