The actual file is written two lines later as:

  test-tool index-version <.git/index >actual

So it seems that neither stdout nor stderr of that 'git add' command
matters.

However, in most of the preceeding tests 'git add's stderr does indeed
matter, as they do:

    git add a 2>&1 | sed "s/[0-9]//" >actual.err &&
    # write expect.err
    test_cmp expect.err actual.err

I suspect that the 2>&1 redirection this patch is removing might have
been a copy-paste error.
