3804	Upload does upload unchanged nodes/ways/relations	andre68@…	team	"JOSM currently uploads nodes/ways/relations even if they have not been changed or the change was retracted by not using undo.

Example 1: Adding a tag to a node und removing that tag afterwards without using undo. Undo is not usable if there were other changes in the meantime. The node is beeing uploaded then which should not be the case.

Example 2: Joining ways. When a node of way1 is joined to way2 then both way1 and way2 are beeing uploaded even though way1 was not modified.

This unnecessarily stresses the OSM server and makes the history of the object unnecessarily long.

JOSM should compare the current attributes of an object with the old state and should only upload the object when there was a real change.
