Sure, try the command below in a shell and you'll get a warning.
echo "( Group: [Node A] [Node B] ) -> [Node C]" | graph-easy --as graphviz
Use of uninitialized value in concatenation (.) or string at
/Users/peredin/perl5/perlbrew/perls/perl-5.18.1/lib/site_perl/5.18.1/Graph/Easy/As_graphviz.pm
line 570, <STDIN> line 1.
Generated output:
--- cut ---
"Node A" "Node C" [ color="#000000", ltail="cluster0" ]
--- cut ---
Expected output:
--- cut ---
"Node A" -> "Node C" [ color="#000000", ltail="cluster0" ]
--- cut ---
Identical lines cut.
I'll try to provide a t/.t when I've figured out if there are any
other cases that cause the same warning to be generated.
