    just a little correction in the pltcl_guide.nr.

    Sometimes I changed the name of tuple arguments to numbers
    like the other args are. Otherwise it wasn't possible to
    create a function as

        CREATE FUNCTION f (EMP, EMP) ... LANGUAGE 'pltcl';

    The arguments are now accessed in the function as

        $1(name) vs. $2(name)
