[gh 17847] data->pos_delta should stick at infinity
The expression we're about to add to data->pos_delta in this part of
study_chunk() can be both positive or negative; however while we apply
an overflow check to avoid exceeding OPTIMIZE_INFTY, we were happily
subtracting from it when the expression was negative, making it no longer
infinite.
