Thanks, Pascal, that's perfect. Don't know how I missed it

Yep, works great.

No big problem, I don't suppose. I guess I'll get used to it.
Just caused me some minor inconvenience when it behaved
unexpectedly (unexpected to me, that is) and undid lots more
than I'd intended. I'm just being more careful now, until
I comfortably know what to actually expect.

Thanks, again, Pascal. That's perfect, too. Just what I wanted,
and had also failed to find (neither that nor anything close to it)
during google searches.

Yeah, I peeked at your informatimago.com homepage, and saw all
your gpl'ed emacs tools. The asm7090 seemed especially unusual.
I started with keypunches (and that's 026's), and ran stuff
on the 7040 in CCNY's EE dept a long (long,...) time ago.
But the creation date on your pjb-asm7090.el is 2005-06-04.
Somebody still emulating that somewhere?
