x/term: prevent invalid indexing into stRingBuffer The exported method (*stRingBuffer).NthPreviousEntry does not correctly handle arguments with negative values. A negative value will index beyond slice boundaries in most cases (unless size = max = INT_MAX) and cause an access violation at runtime. This change adds a condition to return ok = false for all negatively valued arguments, which is the same behavior that occurs with positively valued arguments exceeding buffer length. Adding the capability to index backwards (from the end of the slice) does not seem like the intent of this method, and it would not improve or simplify existing functionality. It would also be inconsistent with the handling of positive values out-of-bounds.
