Passing one instead of 8 or 16 arguments reduces the size of the
generated code somewhat:
add/remove: 2/3 grow/shrink: 1/4 up/down: 1772/-2137 (-365)
There's one more candidate, unique_id_show, but that uses %02X, and I'm
not sure it would be ok to start using lowercase there, so I've left it
alone for now.
