<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">users-guide: Fix a few markup issues

Strangely these were only causing the build to fail in the aarch64-linux

job, despite Sphinx throwing errors in all jobs I checked.

Also changes some `#ifdef`s to `#if defined` to satisfy the linter.
