        * rendering/bidi.cpp:
        (khtml::RenderBlock::bidiReorderLine): Use previousLineBrokeCleanly instead of
        resetBidiAtEnd now that the former is always correct.
        (khtml::RenderBlock::layoutInlineChildren): Use new skipTrailingNewline flag.
        (khtml::RenderBlock::findNextLineBreak): Set previousLineBrokeCleanly for line breaks
        caused by newlines as well. Added skipTrailingNewline flag.
