From: Jeff King <peff@xxxxxxxx> Provide a sane initialization value for `struct ref_filter`, which in a subsequent patch will be used to initialize a new field. In the meantime, ensure that the `ref_filter` struct used in the test-helper's `cmd__reach()` is zero-initialized. The lack of initialization is OK, since `commit_contains()` only looks at the single `with_commit_tag_algo` field that *is* initialized directly above. So this does not fix a bug, but rather prevents one from biting us in the future.
