>Description:
tred program from graphviz-2.20.3 erroneously removes all edges from any graph. This bug is also reported in previous version of graphviz (2.20.2) in debian distribution (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=493494).

Test:

% pkg_info |grep graphviz
graphviz-2.20.3     Graph Visualization Software from AT&T and Bell Labs
% echo 'digraph { a->b->c; }' | tred
digraph {
        a;
        b;
        c;
}

>How-To-Repeat:
% echo 'digraph { a->b->c; }' | tred
digraph {
        a;
        b;
        c;
}
