HOME is set to TRASH_DIRECTORY in t/test-lib.sh already, and we do
so to avoid getting affected by the real $HOME/.gitconfig of the
user who happens to be running the test suite.

With that in place for ages, this test still moves HOME away from
TRASH_DIRECTORY, and that is totally unnecessary if it is only done
to avoid getting affected by the real $HOME/.gitconfig of the user.
After all, this single test is not unique in its need to avoid
reading from user's $HOME/.gitconfig---so I expected there may be
other reasons.

That is why I asked, and your response is not quite answering that
question.
