Description:
------------
Backslashes within user comments may not be getting inserted properly

Reproduce code:
---------------
http://uk3.php.net/manual/en/language.namespaces.basics.php

Looking at the first comment, I think backslashes are being stripped out of some text - this could get very confusing for users new to namespaces who read through the extra comments!

Expected result:
----------------
Im fairly sure the first comment should look like this

<?php
//  namespace MyProject\DB;
require 'db.php';

use MyProject\DB; // fine; same as DB\
use MyProject\DB\Connection as DBC; // fine
use MyProject\DB as HM; // fine
use HM\Connection as DBC2; // class call ends with FATAL!!!

$x = new DBC(); // fine
$y = new HM\Connection(); // fine
$z = new DBC2(); // Fatal error: Class 'HM\Connection' not found
?>

Actual result:
--------------
<?php
//  namespace MyProject\DB;
require 'db.php';

use MyProjectDB; // fine; same as DB\
use MyProjectDBConnection as DBC; // fine
use MyProjectDB as HM; // fine
use HMConnection as DBC2; // class call ends with FATAL!!!

$x = new DBC(); // fine
$y = new HMConnection(); // fine
$z = new DBC2(); // Fatal error: Class 'HM\Connection' not found
?>
