[Bit-dev] Automatically validate docstrings incl. Sphinx python domain directives and roles ("markup language")

During my development of https://github.com/bit-team/backintime/pull/1295 I had to modify a docstring and include references to other functions which can be done by via Sphinx roles, eg.: Args: cfg: A config created via :py:func:`config.Config()` or :py:func:`getConfig()` If would be great to validate these cross references automatically via TravisCI, a new make target or somehow else since generating the Sphinx doc and viewing the formatted doc manually is time consuming (and boring ;-) Could we add this to the TODO list + collect solution proposals?
