Summary0001793: Cannot connect clusters to clusters within themselves

When using the fdp tool to try to create nested style graphs using the
cluster feature, it is not possible to create edges between a cluster
and another cluster within it.

When you try to connect a subcluster
to its parent cluster with an edge, you receive an error message:

An unhandled win32 exception occurred in fdp.exe [3852].
Steps To Reproduce

graph G {

  subgraph clusterA {
    label = "A";
    subgraph clusterC {
    label = "C";
subgraph clusterD {
    label = "D";

    // This works on its own
  clusterD -- clusterC;

    // Doesn't work - cannot connect clusters to clusters within
    // them for some reason
  clusterC -- clusterA;

Additional Information
Please let me know when fixed.

At present, fdp does not support edges from a cluster to a contained cluster. It should have printed
an error message and exited. The unhandled win32 exception is a bug; allowing

  clusterC -- clusterA

is a feature request.
