$.fn.is and $.fn.not should accept DOMelements and jQuery collections

[paul]

This is basically an addition to #2579. I have had this usecase in almost any UI plugin: The simple task, that I want to see if my DOMelement is within the current jQuery set.

Right now, I have to do something like this:

var inset = false; $(..).each(function() {

if(this == myElement) inset = true;

});

This would be /much/ easier and logical if I could simply do

$(..).is(myElement)
