sphinx-rfcsection is a minimal Sphinx extension to add sane automatic titles
to RFC references with sections included.
For simplicity, this extension subclasses Sphinx's built-in :rfc: role from
sphinx.roles.RFC (part of the Sphinx code since version 2.x). Just a small
amount of custom logic automatically sets a custom title on the reference if
appropriate, before delegating right back to the built-in code.
