Use after move in format-inl.h

Line 545 in 0036a1d

int num_bigits = static_cast<int>(bigits_.size());

uses bigits_ after it has been moved. There is further use of bigits_ in that function as well, some of which may be appropriate, some not.

void square() {
    basic_memory_buffer<bigit, bigits_capacity> n(std::move(bigits_));
    int num_bigits = static_cast<int>(bigits_.size());

Good catch, thanks. This access happens to be benign but unnecessary - fixed in 02896da.
