I don't think it worth fixing.  This was IE team deleberate 
decision to stop being detected as IE[1], and I generally agree - 
browser detection is evil and should not be used as soon as there 
are other options.  In nginx, there is no real need to detect IE11 
(and probably nobody cares about IE now anyway).
