The right way to do it is:

  test_config advice.detachedHead false &&
  ...

so that the cleanup runs whether or not you may it to the end of the script.

Hmm. Using "!test_cmp" seems weird to me, just because it would falsely claim success if something else unexpected changes. Our usual method for making sure some particular output does not appear is "test_i18ngrep" with a liberal pattern.
