The previous commit un-broke the "badFileMode" check; before then it was literally testing nothing. And as far as I can tell, it has been so since the very initial version of fsck. The current severity of "badFileMode" is just "warning". But in the --strict mode used by transfer.fsckObjects, that is elevated to an error. This will potentially cause hassle for users, because historical objects with bad modes will suddenly start causing pushes to many server operators to be rejected. At the same time, these bogus modes aren't actually a big risk. Because we canonicalize them everywhere besides fsck, they can't cause too much mischief in the real world. The worst thing you can do is end up with two almost-identical trees that have different hashes but are interpreted the same. That will generally cause things to be inefficient rather than wrong, and is a bug somebody working on a Git implementation would want to fix, but probably not worth inconveniencing users by refusing to push or fetch. So let's downgrade this to "info" by default, which is our setting for "mention this when fscking, but don't ever reject, even under strict mode". If somebody really wants to be paranoid, they can still adjust the level using config.
