patch 8.1.2351: 'wincolor' not used for > for not fitting double width char

Browse Source 
Problem:    'wincolor' not used for > for not fitting double width char.
            Also: popup drawn on right half of double width character looks
            wrong.
Solution:   Adjust color for > character.  Clear left half of double width
            character if right half is being overwritten.
