[PATCH] reduce delta head inflated size

Supposing that both the base and result sizes were both full size 64-bit values, their encoding would occupy only 9.2 bytes each. Therefore inflating 64 bytes is way overkill. Limit it to 20 bytes instead which should be plenty enough for a couple years to come.
