You can't just 'exit 1' mid-script, because terminating the test script
abruptly makes the test harness unhappy.

Both variables are set at this point, so calling plain 'unset' is OK.
Still, I would suggest using 'sane_unset' instead, so the next person
looking at this test doesn't have to spend brain cycles on figuring
out whether plain 'unset' is indeed safe or not.

This whole '#cleanup from the above' block is just ugly.  Not your
fault, of course, but the consequence of how the preceeding tests were
written in the past.  I think it would be best if this series were
scheduled on top of the 't1500 cleanup & modernization' patch I saw a
few days ago, then this block wouldn't be necessary at all.
