patch 9.1.0667: Some other options reset curswant unnecessarily when set

Problem:  Some other options reset curswant unnecessarily when set.
          (Andrew Haust)
Solution: Don't reset curswant when setting 'comments', 'commentstring'
          or 'define' (zeertzjq)

fixes: #15462
closes: #15467
