[issue29634] Reduce deque repeat execution when maxlen exist and size is not 1

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Wouldn't be better to update the number of repeats before the loop rather than checking at every iteration?

if (deque->maxlen >= 0 && n * size > deque->maxlen)
    n = (deque->maxlen + size - 1) / size;
