No, this is something else unrelated to the original change: I'm trying
to coinvince people not to use `select-enable-primary', at least
lightly, and those prior changes you referred to changed the default
value of `select-enable-primary'.  Further down another thread someone
said that was common advice on the internet, which is shocking, since
that amounts to teaching people to break their systems.

We don't know what happens in Noah case yet.  He hasn't replied to my
questions.

Thanks.
