We should not edit the commit message manually after it has been
reviewed.

Either it is automatically added by the review tool, or we need to
gather patch review statistics from the review tool.

The latter has the advantage that post-commit review also counts,
which is not possible if we only consider Reviewed-By: lines in
commits.
