patch 9.0.1578: SpellCap highlight not always updated when needed

Problem:    SpellCap highlight not always updated when needed.
Solution:   Handle updating line below closed fold and other situations where
            only part of the window is redrawn. (Luuk van Baal, closes #12428,
            closes #12420)
