[Merkaartor] Turning waypoints into nodes

[Hugh Barnes]

What is the recommended way to turn a GPS waypoint (loaded locally – does it 
make it any difference?) into a new node?

Here's the background. It's taken me a while to work out. I selected the 
waypoint, deleted its default tags, and in this case, tagged it 
as "amenity=bicycle_parking". Uploading it, I got a 404 error in a dialogue 
box. I actually assumed this was the API service endpoint returning 404, so 
decided to wait a bit. This happened enough that it finally dawned on me that 
this is the API responding - the wiki confirms that this is the response 
provided when updating resources that don't exist in the database. (I always 
thought "412 Precondition Failed" covered these cases, but the API is right.)

OK, so I looked at the online documentation and it doesn't seem to be covered. 
UI guessing fun happened. My strongest guess was to select the waypoint and 
then Create->Node from the menu. A few variations. Short of (I am sure this 
is problematic …) adding my new node right next to that one, so close it's a 
blade of grass, I give up.

Thoughts, list?

Cheers - Hugh
