We tried out to use either v.support or v.digit but snapping only
snaps 2 nodes to 1 single node (or to 2 nodes at the same
location).
We would rather like to convert a node, shared by 2 lines, to a
vertex
of a single line (like Bernhard tried to demonstrate).

Any suggestions? Or perhaps any reason why it isn't sensible to do
so?
