A new point within 25 m of a saved one took that point's key, name and place
link, even when another new point already stood on it. A stop put in just
before a stop a stage starts at took the stage's key, so the stage left its
day and the undo could not bring it back. The saved points are now matched one
to one, the nearest pairs first, so a point standing on a saved one keeps it.
The points a hike is changed through carry no shaping mark, so an inserted or
removed stop and a reshape turned every shaping point into a stop. A via point
standing on a saved shaping point now shapes the line still, unless a stage
ends there.
