fix carry into uninitialized slots during printf floating point rounding
in cases where rounding caused a carry, the slot into which the carry was taking place was unconditionally treated as valid, despite the possibility that it could be a new slot prior to the beginning of the existing non-rounded number. in theory this could lead to unbounded runaway carry, but in order for that to happen, the whole uninitialized buffer would need to have been pre-filled with 32-bit integer values greater than or equal to 999999999. patch based on proposed fix by Morten Welinder, who also discovered and reported the bug.
