append in dc-path%

Adds the sub-paths of a given path to this one. Closed sub-paths of the given path are added as closed sub-paths to this one. If both paths have an open sub-path, then this path's sub-path is extended by the given path's open sub-path, adding a line from this path's current ending point to the given path's starting point. If only one of the paths has an open sub-path, then it becomes (or remains) this path's open sub-path.
