vim-patch:9.1.1419: It is difficult to ignore all but some events (#34245)

Browse Source 
Problem:  It is difficult to ignore all but some events.
Solution: Add support for a "-" prefix syntax in '(win)eventignore' that
          subtracts an event from the ignored set if present
          (Luuk van Baal).
