hi all git format-patch -s is sub-optimal : it appends the SoB, which falls after the snips --- changelog ... that the commit message may contain So it misfires on any maintainer scripts expecting the SoB above the 1st snip. The workaround is manual SoBs above any snips. I note this in -s doc, Add a Signed-off-by trailer to the commit message, using the committer identity of yourself. See the signoff option in git-commit(1) for more information. "trailer" is really "document current working behavior" (normative docu-speak, so to speak;) Ideal behavior is to find 1st in-body --- snip and insert there
