I searched for BANGHIST in the archive, but I couldn't find the relevant
change, the last one is 6542, but there must be one later --- is it
working?

The following ought to work (the first hunk is just because the logic
confused me), but could everybody please try this on the favourite mode of
history usage.  Judging by the fact that it's been there for weeks, nobody
uses nobanghist anyway.

This had better be the last major bug.

I suppose I'm going to be told the following is just how history is
supposed to work?

  % unsetopt banghist
  % echo !!
  !!
  % setopt banghist
  % !!
  zsh: no such word in event

(it recovers after that).
