So you add a div, set it to be 10000px tall, and then remove the div
if the documentElement's *clientWidth* is not 0?
| if (docEl.clientWidth !== 0) {
| // ...
| body.removeChild(div);
| }
I'd say move the removeChild call out of that `if` statement. THough
I'm not sure why you're checking clilentWidth there. SHouldn't that be
a check to clientHeight? I don't get it.
I'd also rename `div` to `testDiv`. Identifier `bs` is good.

In Chrome, I see for both examples:
"Use body's scroll coords? Yes." Yet, the scrollHeight for
documentElement is 10000.
javascript: alert(document.documentElement.scrollHeight);
Chrome/8.0.552.237:
10000

I detected quirks mode by checking the compatMode. SO post here:

Though that is less specific to scroll values, so inferences derived
regarding scroll values won't be as strong as with direct capability
tests.
