Yes. The first string that this utility prints in main() goes to
System.out.
Not sure why the rest would need to go to another stream.

Now, after removing the overload `print(String fmt, Object ... args)`
(which was just an alias of printf(String fmt, Object ... args)), we
have two print() methods, and both of them indent the text.
I am not planning to invest much into this utility, just wanted to fix
that annoying glitch.
With kind regards,
Ivan
