This macro is supposed to make sure an array has enough memory allocated for a given number of elements. Unfortunately, a condition was inverted (I... what???). It only allocated if there was still enough memory left, or only one additional element had to be allocated. Since this macro was only used by MP_TARRAY_APPEND, this case was never actually triggered. It's still utter non-sense.
