Merge branch 'jk/in-pack-size-measurement'

"git cat-file --batch-check=<format>" is added, primarily to allow on-disk footprint of objects in packfiles (often they are a lot smaller than their true size, when expressed as deltas) to be reported. * jk/in-pack-size-measurement: pack-revindex: radix-sort the revindex pack-revindex: use unsigned to store number of objects cat-file: split --batch input lines on whitespace cat-file: add %(objectsize:disk) format atom cat-file: add --batch-check=<format> cat-file: refactor --batch option parsing cat-file: teach --batch to stream blob objects t1006: modernize output comparisons teach sha1_object_info_extended a "disk_size" query zero-initialize object_info structs
