Musing...

If you have:

<p class="foo bar">Fred</p>
<p class="bar foo">Barney</p>
<p class="foo baz bar">Wilma</p>

which should be picked up by getElementsByClassName("foo bar")?

In the "string split" mode, it would pick up all three. However, I
suggest that designers might be misled by this interface into thinking
that it only picks up the first one - which matches exactly.

So I think a multiple-argument interface would remove this possible
confusion, and make things more obvious than a whitespace-splitting
interface.

getElementsByClassName("foo", "bar") ideally, but if that's hard, then
getElementsByClassName(["foo", "bar"]);

So I agree with Brad, I think :-)
