Commit Data (ID: {'C', 'D', 'A', 'T' }) (N * (H + 16) bytes)
* The first H bytes are for the OID of the root tree.
* The next 8 bytes are for the positions of the first two parents
- of the ith commit. Stores value 0x7000000 if no parent in that
+ of the ith commit. Stores value 0x70000000 if no parent in that
position. If there are more than two parents, the second value
has its most-significant bit on and the other bits store an array
position into the Extra Edge List chunk.
