Problem:
Please allow setting minimal subgraph cluster distance.

When increasing mindist, nodesep and ranksep the clusters remain very close together. See example the horizontal distance between cluster with node l and cluster with node a.

clustersep could ba a variable to control the minimal distance between clusters which is not set to a static and not controllable by the user.

Fixing this bug will provide more layout control to the user.
Input:

digraph "test" {
	node [width=1.5 height=1.5 ]
	rankdir=LR
	nodesep=.75
	mindist=1
	sep=0.1
	ranksep=.5
	subgraph cluster_abc {
		style="filled"
		a -> b -> c
	}
	subgraph cluster_def {
		style="filled"
		d -> e -> f
	}
	subgraph cluster_ghi {
		style="filled"
		g -> h -> i
	}
	subgraph cluster_jkl {
		style="filled"
		j -> k -> l
	}
	subgraph cluster_mno {
		style="filled"
		m -> n -> o
	}
	z -> a [lhead=cluster_abc ]
	z -> e [lhead=cluster_def ]
	z -> i [lhead=cluster_ghi ]
	k -> {g d }
}
