[graphviz-interest] bug with splines=curved

Hi,
with the following graph definition the edge between bar and foo does not
get drawn.

If you remove the splines = curved; line it gets ok.

Many thanks.

Tested with 'dot' on windows graphviz built 21040812

input:
strict digraph {
splines = curved;
  bar -> foo
}

output:
strict digraph {
        graph [bb="0,0,54,108",
                splines=curved
        ];
        node [label="\N"];
        bar      [height=0.5,
                pos="27,90",
                width=0.75];
        foo      [height=0.5,
                pos="27,18",
                width=0.75];
        bar -> foo       [pos="e,-1.#IND,-1.#IND -1.#IND,-1.#IND
-1.#IND,-1.#IND
 -1.#IND,-1.#IND -1.#IND,-1.#IND"];
}
