Newlines in labels

[kubajal]

Hi,
is there a way to have a two-line label on a node?

I have the following DOT graph:

# graph.dot
digraph G {
  node_0 -> node_1;
  node_0 [label="aaa \\\\ bbb"];
}

Executing

dot -Txdot graph.dot | dot2tex -ftikz > graph.tex
latex -output-format pdf graph.tex

produces the following image

I.e. it doesn't put 'bbb' on the 2nd line. Is there a way to fix that?

I think this is a very important missing feature.
It is very easy to do in the normal label with \n, it should also be doable in texlbl.
I noticed that in the source code, \n splits the node into two \draw commands. Any reason why the same approach cannot be used here in the ?
