From: Lars Schneider <larsxschnei...@gmail.com>

Use `test_config` to set the config, check that files are empty with
`test_must_be_empty`, compare files with `test_cmp`, and remove spaces
after ">" and "<".

Please note that the "rot13" filter configured in "setup" keeps using
`git config` instead of `test_config` because subsequent tests might
depend on it.
