forbid the use of std::endl on std::cerr

Browse source 
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.
