pure mpatch: avoid using list.insert(0, ...)

In Python lists are implemented as arrays with overallocation. As a
result, list.insert(0, ...) is O(n), whereas list.append() has an
amortised running time of O(1). Reversing the internal representation
of the list should cause a slight speedup for pure Python builds.
