When building the static Huffman tables, it's vital to include the

two unused entries at the end of the lit/len table (286 and 287),
because without them all the 9-bit codes are off by four. I can only
assume I hadn't noticed this before because no test file I've
compressed had both (a) contained byte values >= 0x90 and (b)
required a static block.
