 It wouldn't do that because of the $_quote_style that would be set. But it
 was wrong in another way, so thanks, fixed now.

 given its due date is less than two weeks.

 The vulnerability being addressed could form the basis of a zero-day XSS
 exploit, and has been in the past on other platforms.
