When running `git diff -- $file1 $file2' on large enough files, index_fd() attempts to use 'the_repository->objects', assuming it is initialized, but that's not the case for non-repository usecases.
When git diff is invoked without a backing repository, INDEX_WRITE_OBJECT is never set in flags, meaning only the hash is needed and nothing should be written to the object store.
Enforce the use of index_core() in this case.
