But only sometimes. 2) My *Messages* buffer frequently ends up being narrowed, and that didn't happen before. Is that something that can happen somehow? Or is that totally unrelated? (My *Messages* buffer is 20K lines long and sometimes has lines that are tens of K long.) Like I said, I can't reproduce either thing, which is why I haven't reported it, but I thought I'd mention it in case it's somehow related to this feature.
