Hello, I would lide to propose an enhancement.
As a user, I need several repositories to have my commits both gpg signed, and their messages decorated with the `Signed-off-by:` trailer. This is a requirement to have the contribution accepted by respective communities.
The first part is easy to achieve using `commit.gpgsign=true`, but the latter, not so much.
Caveats with current feature set:
- Passing `--signoff`/`-s` every time is easy to forget. Even more so when some commits can be done by external tools (IDEs doing git pull with merge, etc.)
- Creating Git alias almost get there, but one cannot override what `git commit` does. So one have to remember to use the alias, that is error prone.
- Using custom hooks to pre-prepare the message is a bit more elaborate. Scales poorly with growing number of repositories requiring signoff. Can collide with other hooks touching the message for some other reason.
Possible courses of action:
- Introduce new config option `commit.signoff`, that would be independent of `commit.gpgsign`. It would simply cause `git commit` to always behave like `git commit --signoff`.
- Add 3rd possible value to `commit.gpgsign` to both sign and add trailer.
- Change `commit.gpgsign` semantics to always add the `Signed-off-by:` trailer if set to true. Likely have compatibility implications.
- Train developers to never forget `--signoff`/`-s`, befriend `git rebase --signoff` :-/
I appreciate any feedback. Thanks!
