Be aware that if any command in the &&-chain prior to `git config
--unset` fails, then `git config --unset` itself will not be executed,
hence the cleanup won't happen. The way to address this is to instead
use `test_config` to configure the value since it will ensure that the
value gets "unset" regardless of whether the test succeeds or fails:

   test_config diff.context 8 &&

The same comment applies to all the new tests.
