        - fix http://bugs.webkit.org/show_bug.cgi?id=13153
          REGRESSION: Visual highlighting of pre-populated blank line in textarea is broken

        - fix a bug where selecting across a soft line break did not highlight to
          the end of the first line if it contained skipped whitespace

        * rendering/InlineTextBox.cpp:
        (WebCore::InlineTextBox::selectionState): Changed to treat a selection that ends on the
        end of a hard line break as if it ends after the line break. Fixed the case of a selection
        that starts and ends in the same text object as the box but does not intersect it
        to return SelectionNone instead of selectionBoth.
