When fetching stdout from an execInContainer Result object, an extra newline is added at the end of each frame. In our case, every 4097th char is a newline, which may break up a word.

The problem exists because ExecInContainerPattern.execInContainer() uses ToStringConsumer to collect stdout and stderr. Said classes adds a newline to before all but the first frame of data.

We need the exact output for our tests, and would appreciate a fix, or at least make this behavior configurable.
