LevelDB: Remove excess vector copy
Created attachment 189398 [details] Patch
tony@ - it looks like someone thought they were going to benefit from NRVO optimization, but that isn't possible because the return object is a reference that comes in via a parameter. Instead, we get an extra copy. I did a blame and looked back - this looks like it corresponds to the original checkin of LevelDBDatabase.cpp by hans@chromium.org so it doesn't look like this was any kind of purposefully optimization.
