Your are perfectly right. I modified your proposal a bit, so the
format-string is concatenated only once and not with every insertion:

public define number_lines ()
{
   push_spot;
   if(is_visible_mark, dup) % leave return-value on stack
     narrow;
   eob;
   variable i = 1,
     format = "%"+string(strlen(string(what_line())))+"d ";
   bob;
   do
     { bol;
        insert(sprintf(format, i));
	i++;
     }
   while (down_1);
   if (()) % was_visible_mark
     widen;
   pop_spot;
}

Works for me.
