Re: [PATCH] t5616: make robust to delta base change

> Commit 6462d5eb9a ("fetch: remove fetch_if_missing=0", 2019-11-08)
> contains a test that relies on having to lazily fetch the delta base of

> sent as a non-delta object. This assumption may not hold in the future;
> for example, a change in the length of the object hash might result in
> the tree being sent as a delta instead.
