* Improve documentation with command lines and defaults.
The advanced documentation coverage skipped the simple approach and didn't
explain fully what to do with the sample commands.
Fixes#1413.
* Fix docs indentation in the MySQL connection string options.
* Desultory docs and docs config fixes.

some more work is to be done. That said, it's better than nothing already.
