The checksums in the index file "trailers" are all claiming to be 4 bytes, 
and that's wrong - they're full SHA1 sums at 20 bytes each.

The v2 pack-file _also_ has per-object CRC's, and those are indeed just 4 
bytes each, and are correctly listed as such.

The pack-file itself also has a few more things there, it's not just the 
"PACK" string and then the objects. It has two more 32-bit words: a pack 
file version number and the number of entries in the pack-file (all 
network byte order). It also has its own checksum at the end (20-byte SHA1 
again).

But looks good otherwise from a quick look.
