Solution: When overwriting a double-width character with the 'smoothscroll' marker clear the second half. (closes #12469)

" This test is in a separate file, because it usually causes reports for memory
" leaks under valgrind.  That is because when fork/exec fails memory is not
" freed.  Since the process exits right away it's not a real leak.
