My situation is somewhat unusal -- I'm streaming from a local server that
acts as a proxy, so I want to minimise prefetching (to avoid using up
server resources).  I doubt that the default configuration will suit me,
but that's okay.

What's not okay is that with older versions, I could simply tell my users
to run mpv with "--cache no".  With the new version, I'm going to have to
ship a script.
