Sorry for not being clear. I just meant that unlike "test_config" the
"sane_unset" function won't reset the state at the end of the

Right now it doesn't matter in practice since this is the last test
before "test_done", but as tests are added we tend to leak state between
them, which is why we use these "unset at the end" helper functions.

But unlike with config that doesn't matter in this case, since we want
these unset anyway.

Which, looking at this again, you'd only want if a previous test in the
file was leaking its state. That's not the case, so this isn't needed
and you can just apply this on top:

    diff --git a/t/t7517-per-repo-email.sh b/t/t7517-per-repo-email.sh
    index 06c7c0fb78..e5845b0b86 100755

You don't need to be paranoid and unset these, we already unset GIT_*
variables that aren't on a whitelist in test-lib.sh, see 'A call to
"unset"' there.
