Null bytes in lists were getting eaten during concatenation. To avoid this, we track encoded item widths (which are always 1 or higher) and +can them all together. This likely did not affect any of the other Ethereum code, considering it nearly always measures atoms, and the null byte would be seen as no bytes in that case.
