Description:
------------
By making a 'svn diff' on PHP v3.0 and PHP v3.0.1RC1, I found following changes (which also exists in http://svn.php.net/repository/php/php-src/branches/PHP_5_3/run-tests.php rev 286503 (latest revision):

Obviously the change introduced some PHP syntax errors.

I did some tests and found out the syntax is actually right (at least with PHP 5.2.10 on Ubuntu) :) So it is not a bug, however, I couldn't find any documentation/post/article describing this mysterious syntax. It will be very nice if someone can document it in the Strings section of PHP Manual. thanks

It is a forward compatibility option to pass binary strings.
