patch 8.0.1705: when making a vertical split the mode message isn't updated

Problem:    When making a vertical split the mode message isn't always
            updated, "VISUAL" remains. (Alexei Averchenko)
Solution:   Only reset clear_cmdline when filling all columns of the last
            screen line. (Tom M. closes #2611)
