+//
+// The indices of the trackpoints and of the anchors are the ones of the routing buffers: they only
+// mean something for the `revision` they were read with (`routing_revision`), and the commands
+// that use them do nothing if the selection is not the one of that revision anymore.
+
+/// Replaces the trackpoints `start..end` of the selection by the given ones, in a single segment
+/// (see `RoutingBuffer`). A pure insertion if `start == end`, a pure removal without new points.
+/// `attributes` holds the surface, highway, SAC scale and MTB scale of the new points, as
+/// intervals, and `anchors` the indices among the new points of the ones that become anchors.
+/// Does nothing, and says why, if the revision of the routing buffers is not the given one.
