Otherwise looks fine to me.  I don't know if you want your MathML peeps to sign off or not.  I'm not much help in evaluating the beauty of the Math.

I'm ready to r+ with teh enum.

Much better to use an enum here.  Makes the callsites clearer.

enum OperatorType {
    FenceOperator,
    NormalOperator?
}

createMathMLOperator can even have OperatorType = NormalOperator so most callsites don't have to pass anything if you like.

I added the enum.

I cc'd David C. & Fred on the bug, but they're in Europe & may not see this soon. I don't think it needs their expert MathML review before landing. I'm just adding some space, making our layout look more similar to Firefox and TeX. I think we can't ask them to look at every tweak I make. We'll get plenty of reactions to layout issues from real users soon. :)

LGTM.  I agree, we don't need to consult the mathml council for every tweak. :)

I think it would it would be nice in the future to move the tests to TestExpectations with a comment like "Needs rebaseline after rxxxx" for ports you don't rebaseline. That would avoid making our bots red until we do the rebaseline. Thanks in advance.

Good idea, I will do this.

From what I have checked, Firefox refers to an operator dictionary for Operator spacing. Are there any plans for Webkit to use something similar?

Yes! See bug 99620 (or bug 99623).
