Thanks, Greg - good suggestion regarding `git bisect`. I was able to narrow
it down to a change between 5.8 and 5.9, so maybe that's the next logical
thing to do. None of the config options added between those releases seemed
relevant to the issue, but perhaps one of them is and I just don't realize
it.

You're probably looking for a config option that was *removed* between
those releases.
