* src/print.c (print_actions): Output the handling of `$' as the

traces do: shifting the token EOF.  Before EOF was treated as a
nonterminal.
* tests/regression.at: Adjust some tests.
* src/print_graph.c (print_core): Complete the set of items via
closure.  The next-to-final and final states are still unsatisfying,
but that's to be addressed elsewhere.
No longer output the rule numbers, but do output the state number.
A single loop for the shifts + gotos is enough, but picked a
distinct color for each.
(print_graph): Initialize and finalize closure.
