#8 : Done
...
I'm now of the opinion that this is done at the wrong level in the stack and needs to be redone later; but it works for now.
There's a regression in `open`, but I can't see why.

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.

Much investigation of bignum problems
...
bignum multiply is still not working, but as bignum read and bignum divide depend on it, it's the problem to hit first.

Problem is that reading bignums depends on multiplying bignums...
...
Which doesn't work for the second digit into bignum territory - so it's fine at the boundary...

H'mmm. But although two-cell bignums work, n-cell do not.

Both add and print fail with numbers larger than 2^120

Added unit tests to establish that bignum addition and print work

the bug must be in multiplication.

Now creating the correct internal bignum representation

add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.

Tried to get more sensible printing of floating point numbers
...
Results are quite disappointing. Resolution on long doubles is nothing like as good as I hoped; they're out by one part in 10^20.
All unit tests except one pass, and the one that doesn't is a very minor rounding issue, so I'm calling it good.

almost certainly by writing a non-wide character to a wide stream.
