Except that only a positive offset value is here, as it is always a treated as a negative offset (you can only refer to a base that was before you, as that is the only way to know the base's offset in the pack). > + (the size above is the size of the delta data > + that follows). > + delta data, deflated. > + > + offset encoding: > + n bytes with MSB set in all but the last one. > + The offset is then the number constructed by > + concatenating the lower 7 bit of each byte, and > + for n >= 2 adding 2^7 + 2^14 + ... + 2^(7*(n-1)) > + to the result.
