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.

Re: [PATCH 1/2] Support deeper version numbers (e.g. 2.0.4.x)

[Kris Van Hees]

Actually, please ignore me :)  I totally overlooked that DTrace only supports
up to 3 digits for version numbers.  Changing that would be a much larger
change, and not necessarily worth doing.

I'd say we revert this patch as being incorrect in view of the established
versioning scheme, and number the release currently being prepared as being
2.0.5.
