LGTM (I have to reabase onto it).

[kevina]

LGTM.

Note that there may still be room to improve "ipfs refs local" (for example find . -name '*.data' is still faster), but this simple change should not cause any problems.

@kevina some of the cost of refs local is base58 encoding, that shit is expensive.

@whyrusleeping Sorry ipfs refs local was not made to be taken literally, my benchmark code in ipfs/go-datastore#40 does not attempt to decode the key using base58 and my very informal tests found find . -name '*.data' faster then than the direct method on the graph. I did not report it because it was very informal test.

@kevina ah! gotcha, thanks :)
