My personal build of CMark ✏️
render: added begin_content field.
This is like `begin_line` except that it doesn't trigger production of the prefix. So it can be set after an initial prefix (say `> `) is printed by the renderer, and consulted in determining whether to escape content that has a special meaning at the beginning of a line.
Used in the commonmark renderer.
