mklog: handle Signed-Off-By, minor cleanup
Checks
Commit Message
Consider Signed-off-by lines as part of the ending of the initial
commit to avoid having these in the middle of the log when the
changelog part is injected after.
This is particularly usefull with:
$ git gcc-commit-mklog --amend -s
that can be used to create the changelog and add the Signed-Off-By line.
Also applies most of the shellcheck suggestions on the
prepare-commit-msg hook.
Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
---
This command is used in particular during the dev of the frontend
for the Rust language (see r13-7099-g4b25fc15b925f8 as an example).
Ok for master?
