Expand description

Matches a newline character ‘\n’.

Streaming version: Will return `Err(nom::Err::Incomplete(_))` if there’s not enough input data.

## Example

    assert_eq!(newline::<_, (_, ErrorKind)>("\nc"), Ok(("c", '\n')));
    assert_eq!(newline::<_, (_, ErrorKind)>("\r\nc"), Err(Err::Error(("\r\nc", ErrorKind::Char))));
    assert_eq!(newline::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
