wrap() uses the first element when provided a jQuery object

[AurelioDeRosa]

The documentation of the wrap() method asserts that a jQuery object or a string containing a selector can be passed as an argument. However, in case a selector matching more than one element or a jQuery object containing more than one element is passed, only the first (element) is used as the wrapper.

This detail is not specified and I think it's worth to add it. Any thoughts?

Seems like a good idea. I don't know that I've ever seen it used with a selector to be honest!
