[OSM-dev] JOSM request

I like the JOSM undo feature (and I use it often).  One of my typical
errors could be handled better by josm.

After placing nodes, I'll join the segments and select the waypoint
button to start tagging them.   On motorways, I may have a dozen
segments selected then select a node from the other carriageway
accidentally.

The current JOSM undo feature removes my accidental connection to the
wrong carriageway node, but it also unselects the current chain of
added nodes.

Could undo be changed so that the most recent segment is removed, but
the previous chain of remains selected?
