- * The first four bytes of index formats later than version 1 should

- * This is the case because the number of objects in a packfile
- * cannot exceed 1,431,660,000 as every object would need at least
- * 3 bytes of data and the overall packfile cannot exceed 4 GiB with
- * version 1 of the index file due to the offsets limited to 32 bits.
- * Clearly the signature exceeds this maximum.
- *
- * Very old git binaries will also compare the first 4 bytes to the
- * next 4 bytes in the index and abort with a "non-monotonic index"
- * error if the second 4 byte word is smaller than the first 4
- * byte word.  This would be true in the proposed future index
- * format as idx_signature would be greater than idx_version.
