Signed-off-by vs Reviewed-by

Hi,

Some projects like LibreOffice don't use Signed-off-by, instead usually use Gerrit for code review, and reviewers add a Reviewed-by line when they are OK with a patch. In this workflow it's a bit unfortunate that adding a Signed-off-by line is just a command-line switch, but adding a Reviewed-by line is more complex.

Is there anything in git that could help this situation? I didn't see any related config option; I wonder if a patch would be accepted to make the "Signed-off-by" line configurable, or there is a better way.

Like, would a patch that adds e.g. a core.signedOffString configuration option to make the string customizable welcome?

Thanks,

Miklos
