on.js dead code

[Herman Vierendeels]

on.js

// emiter that works with native event handling
on.emit = function(target, type, event){
...
for(var i in event){
var value = event[i];//dead code??!! var value assigned but not used ??!!
if(!(i in nativeEvent)){
nativeEvent[i] = event[i];
}
}
...

Appears to be valid in that the assigned value is not used. Still appears in trunk.
