When computing changed-path Bloom filters or performing a name-only diff, we do not need the blob contents before completing the diff values. Thus, we do not need to download a pack containing the blobs we do not have on-disk before completing our diff calculation. This prevents downloading every blob in a partial clone during "git log --raw" and "git diff --name-only" commands. Signed-off-by: Derrick Stolee <dstolee@microsoft.com>
