patch 9.1.0082: Redrawing can be improved when deleting lines with 'cursorline'
Problem: Redrawing can be improved when deleting lines with 'cursorline'.
Solution: Use smarter invalidation and adjustment. Remove unnecessary
UPD_VALID as it is already set at the top of the loop. Make
the test for #4862 fail without the fix.
