This double negative caught my attention.  The message is
understandable; perhaps "In none of these tests I see ..." would have
been clearer.

A simple search only points to these two files:

   $ git grep '\s*git.*|\s*tee' "t/t[0-9]*.sh"
   t/t1001-read-tree-m-2way.sh:400:        git ls-files --stage | tee >treeMcheck.out &&
   t/t5523-push-upstream.sh:127:   test_terminal git push --quiet --no-progress upstream main 2>&1 | tee output &&
   t/t5523-push-upstream.sh:134:   test_terminal git push --quiet -u --no-progress upstream main 2>&1 | tee output &&

And the following three changes are in line with the result:

Looks good.

Thanks.
