r=me as long as you can give a satisfactory answer to all the questions about how we know various pointers are non-null

> Source/WebCore/editing/EditingStyle.cpp:651
> +    RefPtr<MutableStyleProperties> difference = getPropertiesNotIn(*m_mutableStyle, styleToCompare);

What guarantees that m_mutableStyle is non-null here?

> Source/WebCore/editing/EditingStyle.cpp:1412
> +        extractTextStyles(document, *mutableStyle, computedStyle.useFixedFontDefaultSize());

What guarantees that mutableStyle is non-null here? Can getPropertiesNotIn ever return null?

> Source/WebCore/editing/EditingStyle.cpp:1548
> +    return fontWeight ? fontWeightIsBold(*fontWeight) : false;

Forgot to mention this last time. I think this is even nicer with &&:

    return fontWeight && fontWeightIsBold(*fontWeight);

> Source/WebCore/editing/EditingStyle.cpp:1559
> +    diffTextDecorations(*mutableStyle, CSSPropertyTextDecoration, baseTextDecorationsInEffect.get());

What guarantees mutableStyle is not null? Can EditingStyle::style ever return null?
