Hi,
The documentation in README_maintainer is a bit outdated
wrt. synchronizing with upstream Emacs.
I have updated the to best of my knowledge in the attached patch. I would
be happy to push it, if there are no objections.
It would also be great if someone would let me know about the mistakes
that are undoubtedly in the draft.

I just noticed that your text talks about 'backporting', and wondered if
that is the clearest term to use. To me, a 'backport' usually means
porting a change or fix from the master or development branch to some
older or more stable branch. Whereas in your text I think it is the
other way round, isn't it? (I.e. the Emacs branch is more stable, and
you are talking about porting a fix that someone has made in that branch
to the Org master.) So perhaps 'forward port' would be clearer?

Right. Thanks for bringing this up.

I suspect that Org's maint (where the Emacs changes land) is generally
more stable than the Org in Emacs's master, but, yes, Emacs's version is
the older version. (Well, with v9.0.9 just synced the versions match,
but maint still has quite a few more commits.)
Since before I took over "backporting" changes from the Emacs repo, it's
been referred to as this. Although I agree it isn't great word choice,
I'd prefer that we remain consistent so that, for example, "git log -i
--grep=backport" remains informative.
But if people think using "backport" is too confusing, I'm OK switching
to another term. Of "forward port" and "propagate" (suggested in this
thread by Eric), I prefer "propagate"---or maybe just "port", though
grepping for that might lead to too many false positives. And if we
stick with "backport", it still might be a good idea to clarify in
README_maintainer that we're abusing the term.

So at least I’m not crazy for "coming up with" it backporting!
So I will keep calling it "backporting" but explain that it is more like
propagating changes from the Emacs repository (back) to the Org
repository.
Thanks,
Rasmus

This pathspec will catch nearly all the changes that should be
considered for backporting. In the process of this sync, I realized
that the check should include a few more files for completeness. I now
add etc/ORG-NEWS and etc/org to the pathspec above. On top of that, the
latest sync introduces od-manifest-schema-v1.2-os.rnc and
od-schema-v1.2-os.rnc to Emacs's etc/schema directory, so I've added
those too.
Anyway, that's just for the record. Together these files should be the
source of very few backports, but I think they're worth monitoring to be
to make sure we don't need to deal with any changes on the Emacs-side.
I'm not sure if you want to document the extended and unwieldy pathspec
here, but it would be
-- lisp/org doc/misc/org.texi etc/refcards/orgcard.tex etc/ORG-NEWS etc/org \
etc/schema/od-manifest-schema-v1.2-os.rnc etc/schema/od-schema-v1.2-os.rnc

No problem to stick with 'backport' if that is the conventional term here. Thanks for considering and explaining the point.

Deleting is fine by me. I don't know if it is useful to anyone else.
