No, there are 41 names in 'backzone' but not in 'backward'.
Africa/Bamako is one example.
In 2014g every name in 'backzone' is also in some other file (e.g., in
'europe') so you won't get any new names by adding 'backzone'. This may
not be true in future releases, though.

Yes. The comment at the start of 'backzone' attempts to explain this
situation; see the part where it says "This file is not intended to be
compiled standalone". Perhaps that bit should be moved to the start....

I think that's wise. It's bleeding-edge experimental right now, and I
wouldn't rely on its format staying the same in the next release.
