patch 9.0.0200: cursor wrong if 'nowrap' and two right aligned text propsv9.0.0200

Problem:    cursor in a wrong positoin if 'wrap' is off and using two right
            aligned text props in one line.
Solution:   Count an extra line for a right aligned text property after a
            below or right aligned text property. (issue #10909)
