        REGRESSION (r16122): min/max widths incorrectly calculated for contentEditable text
        http://bugs.webkit.org/show_bug.cgi?id=11570

        * rendering/RenderStyle.h:
        (WebCore::RenderStyle::isSpace): Added.
        * rendering/RenderText.cpp:
        (WebCore::RenderText::calcMinMaxWidth): For the purposes of calculating the line widths,
        treat non-breaking spaces the same as normal spaces if -webkit-nbsp-mode is 'space'
