For example, it is sometimes better to use this trailer instead of `Co-authored-by:`. Signed-off-by: Kristoffer Haugsbakk --- Notes (series): v2: • Do *not* say *without sign-off*; do mention the precondition that it is signed off, and cover the case when the patch author did not sign off on it • https://lore.kernel.org/git/xmqqse6tnho1.fsf@gitster.g/ • Drop “without a commit message”. It doesn’t seem important. A bare patch is just a patch, not a patch plus a message.
