Major progress, multiply now almost works
...
There's a premature free() somewhere, and I'm not sure why.
Print depends on divide, which is easy, but also on mod and floor (of rationals) which isn't.

OK, my idea that long multiplication is like long addition is wrong.

It's still broken, but it's broken because of fundamental misunderstanding which tinkering won't solve.

OK, adding bignums works; multiplying bignums does not work.

There's no evidence of a bug in reading/printing, because the only way I can currently get a number big enough to trigger the supposed bug is by multiplying, which doesn't work.
