Hmm, I didn't mean that one, and I do not offhand what is wrong
about "! grep" that says "output should not contain this string".

The problem is a "cat" you added outside test_expect_*; the recent
push is to have as little executable outside them, especially the
"set-up" code to prepare for the real tests.

i.e. we have been trying to write new tests (and convert old ones)
like this:

        test_expect_success 'I test such and such ' '
                cat >input-for-test <<-\EOF &&
                here comes input
                EOF
                git command-to-be-tested <input-for-test >actual &&
                cat >expected <<-\EOF &&
                here comes expected output
                EOF
                test_cmp expected actual
        '

not like this:

        cat >input-for-test <<-\EOF &&
        here comes input
        EOF
        test_expect_success 'I test such and such ' '
                git command-to-be-tested <input-for-test >actual &&
                cat >expected <<-\EOF &&
                here comes expected output
                EOF
                test_cmp expected actual
        '
