Sabre23t v4: They render as follows, markdown left, outline right

1/ The post title heading in markdown nodetype add extra newline, it doesn't in outline nodetype that looks better to me.#

2/ I needed to add extra blank node/headline to break the post into two lists. I suggest that change of indentation automatically generate newline for markdown processing.#

3/ Perhaps a good design goal is to have an outline nodetype when changed to markdown nodetype, renders almost exactly the same. Noting that markdown markup allows HTML markup in it.#
