updated for version 7.2.418
Problem:    Vim tries to set the background or foreground color in a terminal
            to -1.  (Graywh)  Happens with ":hi Normal ctermbg=NONE".
Solution:   When resetting the foreground or background color don't set the
            color, let the clear screen code do that.
