In some code paths, Pl_Concatenate is used, which suppresses + that, but in other code paths, it's not used, and the library relies + on the behavior of finish() being called. Then there's the issue of + nested Pl_Concatenate pipelines -- calling manualFinish() on the top + one doesn't call manualFinish() on the lower ones, and there are no + exposed methods that allow us to apply things down the pipeline + stack, so it's hard to fix this without changing the API (at least + making Pipeline::getNext() public, which may be undesirable). To see + this problem in action, stick a Pl_Concatenate in front of the + pipeline in pipeContentStreams and observe the test failure. One + solution might be to add an additional argument indicating whether + or not to delay calling finish() until the end.
