        The moveParagraphs call that ReplaceSelectionCommand
        performs must receive only inline content from createMarkup, 
        or else it will result in another call to moveParagraphs 
        when it performs the move, resulting in infinite recursion.

        * editing/markup.cpp:
        (WebCore::startMarkup): We were only converting a block to
        an inline if it had an inline style declaration or styles 
        coming from matched rules.  Cleaned up this code a bit by 
        handling an element's style separately from its other 
        attributes.
