This seems like a sensible change. Call it getElementsByClassNames()
would make it obvious that if you supply multiple class names, you get
only elements with all those names. And it would be a reasonably obvious
reduction that if you just supply a single name, you would get all
elements which had that one class name.

So we've ended up with:


elem.getElementsByClassNames(["foo", "bar"]);
elem.getElementsByClassNames("foo", "bar");
or both.

Are there similar functions in the DOM at the moment which can take
multiple arguments? Do you pass an array or multiple individual
arguments, or can you do both?
