We package up the failed test output and trash directories for each run.
You can find the one for this case here:

  https://github.com/git/git/actions/runs/8458842054/artifacts/1364695605

It is sometimes misleading because we don't run with "-i", so subsequent
tests may stomp on things. But in this case the failing test is the last
one. Unfortunately, I don't think it shows us much, because the state we
tried to diff is removed by the test itself (both the funny dir and the
index after we tried to add it).

So I don't know if we failed to even create "funny /" in the first
place, if adding it to the index failed, or if the diff somehow failed.

On the plus side, while trying to find the failing CI job, I ran across
and diagnosed two other unrelated failures in "seen". ;)
