Partial clone support of "git clone" has been updated to correctly validate the objects it receives from the other side. The server side has been corrected to send objects that are directly requested, even if they may match the filtering criteria (e.g. when doing a "lazy blob" partial clone). * jt/partial-clone-fsck-connectivity: clone: check connectivity even if clone is partial upload-pack: send refs' objects despite "filter"
