Drainage ditch end node connections

Regarding this changeset:

I've created a drainage ditch that leads from Shull Road to Tinker Creek. In reality, the concrete making up the drainage ditch is part of the curb of the road, so one could say that the ditch and the road are "connected" (i.e. all water that runs down the road will go into this ditch). Should I connect the nodes making up the top end of the ditch to the nodes on the road indicating the connection (they're made of the same concrete), even though the center of the ditch structure does not match up with the center of the road?
Should I connect the ending node of the ditch to the line making up the creek indicating the relationship that the water from the ditch flows into the creek, even though the concrete structure of the ditch does not extend into the center of the creek?

The central 'flow lines' of waterways should generally be connected to each other, see the illustration on the rivers page in the wiki. In this case the lower end should definitely connect to the centreline of the creek. The upper end should also probably be connected to the road as it does drain it, even though roads aren't typically thought of as waterway features.

I should note that the wiki page for ditch indicates that it is not usually used for concrete lined waterways. You may find that waterway=drain is more consistent with the rest of OSM.

There appears to be a discrepancy between the (imported) location of the the creek and the position according to the available imagery (Including Virginia specific imagery). This should probably be investigated and the geometry corrected if the imagery appears to be accurately placed.
