Regression in 1.9.0 from 1.8.3 related to namespaced events

Hi,

If en event gets triggered like this - `$.event.trigger('myEvent.mySpace');` then previously it was possible to listen to this event by binding, for example, `$(document).bind('myEvent.mySpace', ...)` and `$(document).bind('myEvent', ...)`.

This fails after updating to jQuery 1.9 (or 2.0 beta), see this simple demo - http://jsfiddle.net/NnWNL/ - there are two alerts when using older versions and only one with the latest.
