window.event is an IE-only global, related to the strange way that
Microsoft handles event processing. 'Sniffing' for this variable is a
reliable way to ensure that the addEventListener() stuff isn't called
for IE.
I suppose it would be more obvious if the test was something like:
if (window.addEventListener) {
...
}
