[talk-au] People's views on duplicating ref=* on the ways in a route relation.

[Andrew Davidson]

There are a bunch of map notes in the NT flagging issues with route 
numbers changing to alpha-numerical (eg 34 -> B34). The routes have been 
mapped with a ref tag on the ways, which will also have to be changed.

Is this duplicate tagging something we want? I can see it causing 
problems where there are overlapping route numbers. On the other hand, 
looking around, it seems to be a very common style in AU.
