Newlines in labels not parsed correctly.

[PlanetEarthSoftware]

digraph  {
    node [ordering=out shape=box style="filled,rounded" fontname="Arial" fillcolor=white color=white]

    1 [ label="hello"]
    5 [ label="good\nworld" fillcolor=yellow ]
    2 [ label="orphan" fontcolor=purple fillcolor=red ]
    3 [ label="with" style="invis"]
    4 [ label="child"  ]
    1 -> 5 
    1 -> 4 [ label="with" "vnd.sia.label-id"=3 ]
}

Node 5 has the label "good\nworld" which is displayed by dot as

Good
World

Reading the node in DotParser I see the label as "goodnworld" :o(
