        A layout test was added when this bug was fixed, so none needed now.

        Cleanup after:
        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): Removed.
        * rendering/RenderText.cpp:
        (WebCore::isSpace): Added.
        (WebCore::RenderText::calcMinMaxWidth): Use inline function instead of polluting RenderStyle.
