One thing to note is that I don't know why the existing code dropped
the fourth digit from the maintenance series.  The updated one will
give you "1,8,5,3,0" (because I just have a hardcoded ",0" at the
end for no good reason there), and if the missing fourth digit in
the original was a deliberate workaround for this file having an
upper limit of the number of digits (like "four"), this change will
break it, so if that is the case, you may have to count and stop the
loop early, perhaps like...

Add

here, and...

                num_digits=$(( $num_digits + 1 ))
