Refactor: Avoid `std::endl` where it's not necessary (part 3)
The `std::endl` manipulator, except inserting `\n` character, also performs `os.flush()`, which may lead to undesired effects (like disk I/O in the middle of forming data strings). For the `std::stringstream` it also has no meaning. * replace multiple `operator<<` calls on a string literal w/ the only call and the only (bigger) string literal; * replace one character string literal used in `operator<<` w/ a char literal.
