Sorry, that sentence might have been unclear.

In currently proposed implementation getElementsByClassName("foo bar")  
doesn't match class="bar foo", but matches class="foo bar". This implies  
that class attribute isn't just space-separated list of classes.

That's why I propose to make this function use exactly the syntax that  
class attribute uses.
getElementsByClassName("bar foo") should match class="foo bar", class="bar  
baz foo", etc.
