Users may have configured "git merge" to always require GPG signing the resulting commits. We are not running "git merge" to re-create merge commits, but merely to replay merge conflicts, and we will immediately discard the resulting commits; there is no point in signing them. Override such configuration that forces useless signing from the command line with the "--no-gpg-sign" option.
