I just found out that "test_must_fail grep ..." is a common
idiom, so what about:

test_expect_success '--no-signoff overrides am.signoff' '
	rm -fr .git/rebase-apply &&
	git reset --hard first &&
	test_config am.signoff true &&
	git am --no-signoff <patch2 &&
	printf "%s\n" "$signoff" >expected &&
	git cat-file commit HEAD^ | grep "Signed-off-by:" >actual &&
	test_cmp expected actual &&
	git cat-file commit HEAD | test_must_fail grep -q "Signed-off-by:"
'
