That's life, right?!  :-)

;-) That's mine.  I contacted Peter Piwowarski asking if he'd like me
to maintain a backport as soon as I realised that an audacious bpo
depended on having a sndio bpo in the archive.  I'm not sure where two
identical changelog entries for bpo+1 and bpo+2 came from...that's
very strange.  Thankfully my sponsor caught it during the application

It seems I somehow mixed up git-checkout and git-rebase.

Ohhh, I think I'm starting to understand now.  So what happens that
the local master branch gets ahead of the remote without --detach, but
that's ok.  It's ok because git pushes a snapshot of the local changed
state to a remote state is only referenced by the tag.  If for some
reason there was a bug in the debian/%(bpo_tag)s version, that's not
in the debian/version-revision...well, that's where it feels strange
to me.  So then one would make further changes to the local repo,
local master would get further out of sync from remote master, but
that wouldn't matter because the local state of master is only ever
reflected as a tag on the remote?  Had I made my mistake at this
point, it seems like it would have been a huge mess!

This makes sense to me, but I'm still unclear why "git checkout
jessie-backports && git merge debian/version-revision" is preferred
over "git rebase debian/version-revision", when version-bumping the
bpo.  I guess the question is: For a version bump of a bpo, should the
changelog of a new-version bpo mention the previous bpo, or should it
only contain a single "Rebuild for $stable-backports" entry?  The
semantics of checkout+merge seem to favour a bpo changelog that
mentions prior versions (independent parallel branch with coherent
history and imported updates), while the semantics of git rebase seem
to favour a series of bpo forks (branch is a history of forks).  I've
consulted this doc: https://git-scm.com/docs/git-rebase

Mattia, thank you for taking the time to help me understand,
I appreciate it a lot,
