It is precisely what I call semi-relative. Do you know of any software
that outputs this kind of URL?

I know software that produces file:/// URLs with percent encoding, so
FFmpeg needs to accept them. But file:/ with percent encoding, I do not,
and therefore we have freedom over them.

Indeed. Or we can make a smarted detection: check if there are percents
and they are followed by hex digits.

This is the ultimate goal, of course.
