Nothing I know about. ROS_INFO() and other ROS logging services send messages to a central logging facility where they are collected from many nodes. Sending incomplete messages does not make much sense in that environment.

You can accumulate a message string in your own code, waiting until a complete line is constructed before logging it. For that, the standard C++ or Python string operations are sufficient.
