    forbid the use of std::endl on std::cerr · 09c93a3a
    Alexandre Duret-Lutz authored
    std::cerr will flush after each operator<< by default, so it's simpler
    to use \n instead of std::endl, especially if we can merge \n into the
    previous string.  Ideally we should prefer \n for std::cout as well,
    but there are reasonable cases where we want to call std::endl there,
    so it's hard to enforce.
