The repo looked too big, as if it had at least partially done that
mistaken create without excluding .nobackup. Although a check
--verify-data did not complain.
I decided to start from scratch for various unrelated reasons.
However, I made a different mistake this time, and the repo won't allow
creations of any more archives as a result. Here are the details:
$ borg init --encryption none borgrepo
$ borg create --exclude-if-present '.nobackup' --stats borgrepo::first /home/me
$ borg create --exclude-if-present '.nobackup' --stats borgrepo::second /home/me
all worked, then the mistake (the actual user name wasn't 'me', so the
actual typo wasn't 'notme' - it was a single letter omission):
$ borg create --exclude-if-present '.nobackup' --stats borgrepo::third /home/notme
/home/notme: [Errno 2] No such file or directory: '/home/notme'
---> ^C'ed it here - immediately after the error message, and
retried without the mistake:
$ borg create --exclude-if-present '.nobackup' --stats borgrepo::third /home/me
Archive third already exists
it made the archive, or part of it, even though it had no source:
$ borg list borgrepo

Sure, once I do adequate testing and have this all scripted, there
won't be anymore such pilot errors. Still...
