-'WebRequestGetPathInfoRequestURI': while extracting path info from REQUEST_URI.
- Allows an extension to extend the extraction of titles from paths.
- Implementing hooks should follow the pattern used in core:
- * Use the `$matches = WebRequest::extractTitle` pattern
- * Ensure that you test `if ( !$matches ) {` before you try extracting a title

-$path: The request path to extract a title from.
-&$matches: The array to apply matches to.
