That is not correct.  The ofs_delta is encoded as an n-byte offset
that is subtracted from the current object's first byte (the byte
holding the type/representation field and first 4 bits of length).

Right.  Saying just "n-byte offset" can be mistaken as the offset from the
beginning of the file, and making it clear that it is relative is good.

The n-byte encoding for an ofs_delta is different then the one
used for the length.  We add 1 for each byte where the MSB is 1.
We also store the data in big-endian form (the most significant
byte is first and the least significant byte is last).

Ah, I forgot about that one.
