But I didn't put much effort in this, as it is
theoretically impossible, which you will see perhaps,
when executing the code.
I line may consist of 16 not bold characters.
After making them bold, the line may consist of
15 characters and should not be bold. If removing
bold, it will consist again of 16 characters....
