 boost::read_graphviz() is a function that reads a graph in graphviz dot
 language from a stream. These graphs are of the form

 [ strict ] (graph | digraph) [ ID ] '{' stmt_list '}'

 e.g.

 graph {
   0;
   1;

   1 -- 0;
 }

 However boost::read_graphviz() does not stop reading at the terminating
 }. Instead it goes on reading until EOF. This is bad when reading from a
 stream that is not an ifstream from a file containing exactly one graph.
 boost::read_graphviz() should stop reading after the terminating }.
