patch 8.0.0290: cursor positioning wrong if wide character wraps

Problem:    If a wide character doesn't fit at the end of the screen line, and
            the line doesn't fit on the screen, then the cursor position may
            be wrong. (anliting)
Solution:   Don't skip over wide character. (Christian Brabandt, closes #1408)
