The following snippet reproduces the problem:

std::ostringstream os;

os << "Hello" << std::endl;  
{
  IndentedStream os1(os, " [prefix] ");
  os1 << "," << std::endl;
  {
    IndentedStream os2(os1, " [another prefix] ");
    os2 << "World!" << std::endl;
  }
}

std::cout << os.str() << std::endl;

Expected output:

Hello
 [prefix] ,
 [prefix]  [another prefix] World!

Actual:

Hello
 [prefix] ,
 [prefix] ,
 [prefix]  [another prefix] World!
 [prefix]  [another prefix] World!
