patch 9.0.1602: stray character visible if marker on top of double-wide char
Problem: Stray character is visible if 'smoothscroll' marker is displayed
on top of a double-wide character.
Solution: When overwriting a double-width character with the 'smoothscroll'
marker clear the second half. (closes #12469)
