Module sections 

Splitting a markdown body into sections and joining it back.

A body splits at its ## headings. A ## block larger than the limit splits further at ### , then at blank lines, then at line ends, and a single overlong line at a character boundary. Headings inside code fences are text. The split is lossless: join of split gives the body back whenever it opens with its # title line.
