Description
Previously, empty arrays with different offsets compared as different because their axes compared as different.
In Julia master (JuliaLang/julia#32348), empty ranges are now equal, making OffsetArray([],-1) == OffsetArray([], -2).
I'm not sure what the right semantic is here; I believe this was untested in the entire ecosystem.
