Numerous Sphinx warnings messing up the logs

For example :

/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions:3: WARNING: Inline interpreted text or phrase reference start-string without end-string.
/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions:3: WARNING: Inline interpreted text or phrase reference start-string without end-string.
/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions.get_transition:1: WARNING: Inline interpreted text or phrase reference start-string without end-string.
/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions.get_transition:1: WARNING: Inline interpreted text or phrase reference start-string without end-string.
/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions.get_transition:1: WARNING: Inline interpreted text or phrase reference start-string without end-string.
/flatland/flatland/flatland/core/transitions.py:docstring of flatland.core.transitions.Grid4Transitions.get_transition:7: WARNING: Unexpected section title.

Running tox . inside the code repository should reproduce these.
