We do, but RUN_SETUP will happily go up to find the .git/ next
to t/ directory that is the parent of trash/ directory, in which
the tests run, without reporting errors.  As parseopt does not
depend on anything in git, this will not do any harm other than
falsely succeeding the test that should not pass.

We could probably introduce an environment variable, GIT_CEILING,
that tells the setup_git_directory_gentry() never go up beyond
that point, and set it to the t/trash directory while running
the test.

Something like that may have other uses in practice.  Often
people wonder what would happen if there is /.git repository and
they would want to make sure they would not accidentally add to
the repository controlled by /.git when they have bunch of other
repositories /some/where/.git in which they usually work.
