Comment (by Umbercode):

 I had some time so I thougth some more on this "problem". As I see it we
 have the following possibilities:

 - !IE
 - (!IE)
 - !IE x   (where x is a version number)
 - (!IE x)
 - !IEMobile
 - (!IEMobile)
 - !IEy  (where y is any string that microsoft in the future might add)

 So short of a regex I think we just need to decide which one triggers the
 requested behaviour.
 Since !IE x  and !IEMobile can mean just targeting any IE or IE derivative
 we can safely assume that we want this behaviour only on !IE or (!IE), if
 needed we can implicitly add it (e.g. if we also want to add all non-IE
 browsers to <!--[if !IE 7]>--> we can "force" this by using <!--[if (!IE
 7) | (!IE)]>-->
 As such I propose we designate (!IE)  as the trigger, this eliminates the
 possibility for false positives like !IE 8, !IEMobile, !IE4 etc.
 I attached a new patch for this.
