Bugfix
* In the bignum module, operations of the form (-A) - (+A) or (-A) - (-A)
with A > 0 created an unintended representation of the value 0 which was
not processed correctly by some bignum operations. Fix this. This had no
consequence on cryptography code, but might affect applications that call
bignum directly and use negative numbers.
