Most of the references to code and settings in the docs were wrapped
in single tickmarks (`), while reStructuredText syntax actually calls
for double tickmarks for inline literals, which are normally rendered
as monospaced text with spaces preserved. Converted the relevant
instances to inline literals, along with some other minor fixes.
Added some more notes about how this is working on the documentation. I do think
that the overall structure is clearer now, and easiest to understand. After all,
that's how it should always be !
