Hmm, if nobody has a comment on this I'll push this change, because the
problem this solves is a pretty frustrating annoyance.

Does that look OK?  Thanks.

I pushed it.  If this is the wrong procedure for these things, please
let me know, apologies in advance.

Thanks.

Lars, I (or git, I'm not sure) got mighty confused and pushed the wrong
branch/worktree to master.  How do I rectify this problem?  Thanks, and
many apologies.

Oops.  😀

I think you just have to revert the commits.

Thanks, how do I do that?  (Also, could my use of multiple git worktrees
cause this problem?)

I.E. can I do a reset and a force-push?

git revert on each of the five commits.

> I.E. can I do a reset and a force-push?

No, that wouldn't allow people tracking the tree to continue working, if
I understand correctly.
