isWindow check in $.isPlainObject is redundant

[carson@…]

By using jQuery.isWindow(obj) in the first line of $.isPlainObject, we're being redundant, because the first condition is !obj, but $.isWindow is basically !obj along with typeof obj === 'window'. So we're actually performing an obj == null check twice. Solution: use only typeof obj === 'window' instead.

I assume you don't actually mean obj === 'window' ie. the string "window"?

Is the use of jQuery.isWindow causing some buggy behaviour? How would jQuery benefit from having two different pieces of code doing the same thing, versus one shared?
