Description
In jQuery 1.6.4, jQuery.extend may not work well, when a boolean value is not specified at the first argument.
1) jQuery.extend(target, obj1)
2) jQuery.extend(false, target, obj1)
I expect the same object will be returned both 1) and 2).
But 1) and 2) sometimes return the dirrent objects.
At line 328 of jquery-1.6.4.js, there is "target = arguments[0] || {}". When argument[0] value is false, target is set to {}.
Then "target = arguments[1] || {};" and "i = 2;" at line 336-338 will not be processed, because "if ( typeof target === "boolean" )" at line 334 will not be true.
