Partial insertion sort the order of elements returned by std::partition is implementation defined (since not stable) and could depend on the version of libstdc++ linked.

Implementation based on a patch by mstembera (, which suggests some benefit by itself. Higher depth moves are all sorted (INT_MIN version), as in current master.
