OK. Works for me.

In the case of the media doc, it is actually a matter of building
one rst file (linux_tv/index.rst). For that, I'm equally happy
if we specify it via <sourcedir> or via <filename>.

I suspect we'll end by needing filenames granularity in some future,
but, if you find easier to just handle <sorcedir> for now, that's
OK.
