Description:
------------
This change (http://cvs.php.net/viewvc.cgi/php-src/ext/standard/mail.c?
r1=1.106&r2=1.107) adds "\r\n" after the X-PHP-Originating-Script 
header, on *NIX machines using "\n" as new line separators, this results 
in *two* line breaks which breaks the email.

This worked fine in PHP 5.2.x but since upgrading to PHP 5.3 it has 
stopped working.

Expected result:
