        <rdar://problem/3933665> smart delete seems to delete too much after expanding selection with arrow keys

        Fixed by updating the selection granularity.  Only byWord granularity enables smart delete, but in this
        case the granularity changed from byWord to byCharacter.

        * khtml/khtml_part.cpp:
        (KHTMLPart::setSelectionGranularity):
        * khtml/khtml_part.h:
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge rangeByExpandingSelectionWithGranularity:]):
        (-[WebCoreBridge rangeByAlteringCurrentSelection:direction:granularity:]):
        (-[WebCoreBridge alterCurrentSelection:direction:granularity:]):
