 Unfortunately it's a common issue with WordPress feeds that they end up
 having a leading whitespace or a linebreak before the XML header. Thus
 fetching RSS feeds with SimplePie fails with messages like:


 {{{
 PHP Notice: This XML document is invalid, likely due to invalid
 characters. XML error: Reserved XML Name at line 2, column 38 in
 /home/wordpress/wp-includes/class-simplepie.php on line 1446
 }}}

 In order to make the SimplePie class resistant to this error, a simple
 trim function should be introduced on the raw data before further parsing:


 {{{
 1605c1605,1606
 <               $this->raw_data = $file->body;
 ---
 >               // whitespace before XML resistance
 >               $this->raw_data = trim($file->body);
 }}}
