Comment (by dcoudert):
I propose to add extend the tests in the following way. Let me know if you
agree before I push a commit.
{{{
sage: g = graphs.PetersenGraph()
sage: filename = tmp_filename(ext=".pajek")
sage: g.export_to_file(filename)
sage: import networkx
sage: h = Graph( networkx.read_pajek(filename)
sage: g.is_isomorphic(h)
True
sage: filename = tmp_filename(ext=".edgelist")
sage: g.export_to_file(filename, data=False)
sage: h = Graph( networkx.read_edgelist(filename)
sage: g.is_isomorphic(h)
True
}}}
Relying on vertex names is unfortunately not possible yet since the read
method turns vertex id like `13` to `u'13'`.
