testing a thing

Sometime last year I had half of a great idea for better Asciidoctor handling in Hugo. I might have the other half now:

• keep my content in the content folder.
• Use adoc.txt for the extension so Hugo ignores it.
• Point my build-adoc script there instead of a neighboring adoc folder.
• profit?

Would work for reStructuredText too.

Need to get through a few post cycles to see how it works.
