        Removing indent from list moves the caret to the line below

        No new layout tests needed because the new results
        for these tests and the removed FIXMEs cover the bug fix:

        Removing indent from list moves the caret to the line below

        Selection preservation during indent, outdent and list
        operations uses rangeFromLocationAndLength.  Ranges returned
        by rangeFromLocationAndLength were incorrect for locations
        just before the line breaks that are emitted after blocks.
        This is because TextIterator emitted bad ranges for these line
        breaks (ranges that started and ended *after* the block).
        The fix corrects the start but not the end.  This is acceptible
        because there is code in rangeFromLocationAndLength that corrects
        the ends of runs using the start of the run and VisiblePosition
        creation.

        * editing/TextIterator.cpp:
        (WebCore::TextIterator::exitNode): Emit a position *inside*
        the block, after its contents.
