Hi there :)

couple of things:

Please use better comments on your changes. You're touching huge relations here which is always dangerous and everybody here would like to knwo what you're doing and why.

Also: Even if a boundary stone sits on top of a border it doesn't need to be connected to the border way (boundary) because the boundary is virtual. You can add it to the relations, though.

Short boundary parts don't need to be namend. The relation has a name, that is enough.

If you're looking for help, please join the community at c.osm.org
There are always helpful people online :)
