        Breaking in the middle of the word
        is allowed only if no breaking opportunity between words has occurred yet. The
        first position on the line should not be considered "between words" even if
        it is a breaking opportunity.

        * rendering/bidi.cpp:
        (WebCore::RenderBlock::findNextLineBreak): Changed according to the above. Also
        cleaned up a couple of lines.
