        * page/Frame.cpp:
        (WebCore::Frame::findString): When comparing the found range with
        what's currently selected a) build a selection with the found
        range to remove collapsed whitespace and b) compare ranges 
        instead of selection objects to ignore the way that the 
        current selection was made (to ignore the base and extent).
