Woops, I was too hasty on this.  More changes are needed...  See the following:

        if (current) {
                $0 = versions[idx[n]];
                if ($3 == 0)
                        printf "%s.%s", $1, $2;
                else
                        printf "%s.%s.%s", $1, $2, $3;

                exit(0);
        }

Obviously, we need to account here also for the possibility of 4 digits, and
then again in all the other places where we output version numbers.
