Added files:

Log message:
        The computation of nullable is broken: it doesn't handle empty
        RHS's properly.
        * tests/torture.at (GNU AWK Grammar): New.
        * tests/sets.at (Nullable): New.
        * src/nullable.c (set_nullable): Instead of blindly looping over
        `ritems', loop over the rules, and then over their rhs's.
        Work around Autotest bugs.
        * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
        frame, because Autotest understand lines starting with a `+' as
        traces from the shell.  Then, they are not processed properly.
        Admittedly an Autotest bug, but we don't have time to wait for
        Autotest to catch up.
        * tests/regression.at (Broken Closure): Adjust to the new table
        frames.
        Move to...
        * tests/sets.at: here.
