[graphviz-interest] concentrate=true failing when compound=true is used!

Hi,

I have the same problem as Ben. I have a pretty complex graph which contains
many subgraphs, almost ALL have nodes interacting with one another so atm
the edges look like a mess.

Ideally, I wanted to limit the arrow to point to the cluster's outer
boundary, and I could do that with "compound=true". Then I wanted that edges
sharing part of the path to merge or join as much as possible before
splitting. That should be achievable using "concentrate=true".

The problem is, compound and concentrate do NOT work together! An error is
generated when i set both attributes to true. Only one of them can work at a
time...

Do you know a work around for this?

Also, I would like to make several edges pointing to the same node, share
the same arrowhead. Is this possible?

Thanks,
Dina
