Title: Clarified that closest() returns 0 or 1 element /per original element/.

I don't think the [`closest()`](http://api.jquery.com/closest/) documentation is clear that it will return 0 or 1 element *per original element*:

> Get the first element that matches the selector

> The returned jQuery object contains zero or one element

This patch is an attempt to clarify that.
