7489	[patch needs rework] Undo merge and download actions	joshdoe	team	I'm just starting to look at the code for this, and I think I'm seeing why a command isn't used for the replace action; it's complicated. However I'd like to know if this is the only reason a command isn't used for this, or if there's some factor which makes it nearly impossible to implement. For anyone interested start looking in [source:josm/trunk/src/org/openstreetmap/josm/actions/MergeSelectionAction.java], [source:josm/trunk/src/org/openstreetmap/josm/data/osm/visitor/MergeSourceBuildingVisitor.java], and dive from there.	enhancement	new	normal		Core			redo undo merge download command stack	olejorgenb
