Cleanup ReST format issues

* ReST doesn't allow monospace in italic sections.
      bash$ grep -R \`\` doc/build/html/ --include "*.html"
* The code-block section "::" needed an empty line before the code,
  otherwise it gets shown in the HTML output.
      bash$ egrep -R "<dt>::" doc/build/html/ --include "*.html"
* Monospaced font incorrectly marked with a single back tick
      bash$ egrep -nR '\w`(\s|[\.,;:])' doc/source/ --include "*.rst"
