regression: unbind namespaced event from window can create recursion in Opera

[trixta@…]

If sveral namespaced events are bound to the window object and someone has used doubble whitespace to seperate the events, Opera throws an error: "Uncaught exception: RangeError: Maximum recursion depth exceeded"

Additionally all browsers add a listener for the event "undefined".

You can see an example here: ​http://jsfiddle.net/trixta/qGkLg/

Although it's a small issue, jQuery either should throw an error, if someone uses doubble whitespaces or should deal with doubble whitespaces.

The docs say "Multiple event types can be bound at once by including each one separated by a space:"

...Not multiple spaces
