I was specifically talking about the unsetting of GIT_COMMITTER_EMAIL,
not the configuration variables.
An easy way to try one step without the environment without
affecting later tests would be to run the above in a subshell,
perhaps like
test_config user.email ... &&
test_config user.signingkey "" &&
(
safe_unset GIT_COMMITTER_EMAIL &&
test_must_fail git push --signed ...
) &&
