**Blush**. I should have caught this during the review. Thanks.

If it were intentional, the caller of apply_autostash() must be
expecting to see an error message from its standard output and
prepared to do something interesting with it, which I do not see, so
I agree that it is a typo. Thanks.
I wonder if this line in 3320 is doing what it meant to do:
test_must_fail git notes merge z 2>&1 >out &&
test_i18ngrep "Automatic notes merge failed" out &&
grep -v "A notes merge into refs/notes/x is already in-progress in" out
