Segmentation and newlines in ner.manual

@KMLDS Thanks for sharing your use case – that’s pretty interesting and I see your point about formatting the data as a list or adding other visual hints. Something similar also came up on this thread. I’ve shared some of my thoughts and the possible complications around this on that thread as well. I still don’t have a perfect solution in mind, but I’m sure we can come up with something that works across use cases!
