Demo does not test/showcase ``.. content::`` directive

[latosha-maltba]

The demo document (more precisely src/demo.rst) does not showcase the ..contents:: directive. The ..content:: directive is present but assigned the :local: parameter so that only headings in that section are reference. However that section does not provide any further headings and as a result the .. contents:: directive does not provide any output.

Possible solutions: a) Remove the :local: parameter, that way all headings of the entire document are collected, shown and referenced. b) Add some (dummy) subheadings in the section of the ..contents:: directive, so these headings are collected and shown. In this case it might also be worth adding sub-sub-headings, so that the layout of nested sections in ..contents:: is observed.

Sidenote: It might or might not be worth adding :backlinks: none parameter to ..contents:: depending on what one wants to demonstrate.

If you like, I'll provide a pull request, though you must point out which solution you'll like to see.

Since I didn't get an answer, I did something(tm).
