We call `get_oid_hex()` in this function, which ultimately ends up
accessing `the_repository` via `the_hash_algo`. We should likely convert
those to `repo_get_oid()`.

There are also other accesses to `the_hash_algo` in this function, which
should be converted to use `state->repo->hash_algo`, as well.

The calls to `read_mmblob()` also end up accessing `the_repository`.

Other than that the patches look good to me. Thanks for working on this!
