Regression test `println!()` panic message on `ErrorKind::BrokenPipe` No existing test failed if the [`panic!()`][1] of the `println!()` family of functions was removed, or if its message was changed. So add such a test. [1] https://github.com/rust-lang/rust/blob/104f4300cfddbd956e32820ef202a732f06ec848/library/std/src/io/stdio.rs#L1007-L1009
