Bug #37937 for GraphViz: Line-formatting for labels does not work

\l, \r, and \c in node labels seem to not work here (graphviz 2.18 installed on Gentoo Linux with GraphViz version 2.03). I expected the code below to produce left-aligned lines. They are, however, centered. See the attachment. Bug in graphviz in GraphViz or am I getting something wrong? This is the script: #! /usr/local/bin/perl -w use strict; use GraphViz; my $g = GraphViz->new; $g->add_node('\lShort line\n\lA long line for testing justification\n'); print $g->as_png;
