.... and in replying to correct me demonstrates the exact point I
was making - that documenting what configuration should be used to
avoid the warning acheives far more than just reporting an error.

i.e. all those people who /don't follow git development/ and have
working configs that pre-date the "auto mode" or it being made
the default now know the correct way to configure their repository.
