In that case it is likely to be extraBit as that is now used and is
different to how I used to think it worked.  There may still be something
to find out about how it works.

Yes, I suppose I expected that a .mp file will always supply everything it needs.
That may just be wrong though, in which case will have to add the same code
as for the OSM conversion.
