updated for version 7.3.1277

Problem:    In diff mode 'cursorline' also draws in the non-active window.
            When 'nu' and 'sbr' are set the 'sbr' string is not underlined.
Solution:   Only draw the cursor line in the current window. Combine the
            'cursorline' and other highlighting attributes. (Christian
            Brabandt)
