Decompressor bug?

    switch b[0] {
    case 0xFF:
        io.ReadFull(c.r, c.buf[:])
    case 0x00:

I think you need to read a byte and set c.raw after io.ReadFull. :-)

my commits up to and including 9ba8f22 and 78bdc8a fix the decompressor (packed -> unpacked binary) code. You can pull these from my fork's master branch.
