Problem:  Vim crashes when an autocommand that is triggered by setting
          'eventignore' or 'eventignorewin' changes that option again.
          This happens with plugins that use ":noautocmd" in an
          autocommand for an event that is checked in the main loop.
Solution: Trigger the events with a copy of the old value in effect, so
          that the value the caller is still using is not freed.  Keep
          the window that holds 'eventignorewin' from being closed while
          the events are triggered.
