> In the absence of a real analysis, the intuition is simply that "t ^= t << 7" will clear masses of leading sign bits when hashing "small" negative integers.

That's a clever solution. If you want to go that route, I would rather suggest t ^= t << 1 which is essentially the same fix but which has probably less collisions on the low-order bits.
