'\n' inside output discarded

Describe the bug
When debugging a program that outputs strings containing '\n', the output is split at each '\n'. If the output includes multiple consecutive '\n', these newline characters are discarded.

To Reproduce
If debugging a C++ program with a statement like std::cout << "aaa\n\n\n\n\nbbb\n\n\n" << std::endl;, pygdbmi presents two separate output messages containing "aaa" and "bbb", respectively. The information regarding the quantity of '\n' between them is not retained.

Expected behavior
The '\n' characters should be preserved as-is within the program's output.
