The pack-file format is slightly different from the traditional git object format, in that it has a much denser binary header encoding. The traditional format uses an ASCII string with type and length information, which is somewhat wasteful. A new object format starts with uncompressed binary header followed by compressed payload -- this will allow us later to copy the payload straight to packfiles. Obviously they cannot be read by older versions of git, so for now new object files are created with the traditional format. core.legacyheaders configuration item, when set to false makes the code write in new format for people to experiment with.
