Patch v2

Almost all of the suggested change has been taken, but some not:

> Source/WebCore/editing/EditingStyle.cpp:344
> +    m_mutableStyle = style.mutableCopy();

Can this be moved to the initializer list now?

No, it could not be moved to initializer list, because style could be nullptr.

> Source/WebCore/editing/ReplaceSelectionCommand.cpp:489
> +        RefPtr<EditingStyle> newInlineStyle = EditingStyle::create(*inlineStyle);

Why is this safe? There is a null check right after...

This change has been removed from the patch.

> Source/WebCore/editing/ReplaceSelectionCommand.cpp:791
> +    RefPtr<EditingStyle> style = EditingStyle::create(*wrappingStyleSpan->inlineStyle());

Why is this safe?

This change has been removed too.
