        Fix for this bug:

        <rdar://problem/3844662> REGRESSION (Mail): Style changes can affect adjacent, unselected text

        * khtml/editing/htmlediting.cpp:
        (khtml::ApplyStyleCommand::doApply): Move end position downstream to be sure we remove style from
        everything that could be affected.
        (khtml::ApplyStyleCommand::removeCSSStyle): Comma in intended function call was outside the
        braces, making it act as a comma operator, with a zero value as the right value!!! This made
        an important check always fail!!! It turns out that we do not want the constant at all, since
        that constant is only needed when checking a computed style, not an inline style as is being
        done here.
        (khtml::ApplyStyleCommand::removeStyle): Call nodeFullySelected with new interface.
        (khtml::ApplyStyleCommand::nodeFullySelected): Change interface and implementation to rely on
        RangeImpl::compareBoundaryPoints to perform the required check.
        * khtml/editing/htmlediting.h: Changed nodeFullySelected function interface.
