Hi All,

You can publish your merged branch somewhere, and others can use
contrib/rerere-train.sh to learn from the resolution.

Supposedly, I've never actually used it...
Does the contrib/rerere-train.sh actually work? I'm reading the code
to ensure I understand what rerere/redo is doing, and in the training
it tries to detect MERGE_RR via L87

     if test -s "$GIT_DIR/MERGE_RR"

It's not clear if that is an internal implementation detail, or a
mistaken use of a historic path name. Can anyone enlighten me?
Historic? No, this is path.c now on master:
Hmm, I'd now agree it's not a mistake, but the implementation detail is historic. I've now found [1,2,3,4] from before I knew of Git! And it's not mentioned in any of the documentation.

     path.c:1454:REPO_GIT_PATH_FUNC(merge_rr, "MERGE_RR")

Internal, sure. We don't document it so it could change in theory, but
then we'd probably change rerere-train.sh along with it...
Hopefully it'll be integrated into rerere/redo before that ;-), along with a bit more documentation on the capability for those who arrived late to the party. The use of this implementation detail came up yesterday in [5].
The tricky part is when the patch series doesn't apply so the
conflict isn't yet on any branch..
When copying patches across to Git for Windows, the conflict
resolution can be tricky.
