A new SUDO prerequisite is provided that does some sanity checking
to make sure the sudo command that will be used allows for passwordless
execution as root and doesn't mess with git execution paths, but
otherwise additional work will be required to ensure additional
commands behave as expected and that will be addressed in a later patch.

Most of those characteristics make this test mostly suitable only for
CI, but it could be executed locally if special care is taken to provide
for some of them in the local configuration and maybe making use of the
sudo credential cache by first invoking sudo, entering your password if
needed, and then invoking the test by doing:

   $ IKNOWWHATIAMDOING=YES ./t0034-root-safe-directory.sh

Hmm. I would like to suggest that we can side-step all of these issues
(and the ones I outline below) by considering a similar approach to the
one Stolee took in t0033: use one or more `GIT_TEST_*` environment
variables to pretend the exact scenario we want to test for.

That's an excellent suggestion. Trying to use sudo in the tests leads to 
all sorts of issues, if we can use a GIT_TEST_* approach instead that 
would be much better.

Best Wishes
