I suggest #2, which implies consistently treating the first argument
passed to the function as a single class name to match (this means
"foo bar" would always return no elements, since a class name
obviously cannot contain whitespace).  Special-casing "foo bar" and
other values seems to be adding complexity without much return.

If multiple class names really need to be handled, my suggestion would
be to take a single array as a parameter, e.g.
`getElementsByClassName(["foo"])` and `getElementsByClassName(["foo",
"bar"])`.
