This means that it is part of the "path" component of the URI, used to
separate and disambiguate, but does not say anything about how that is
interpreted as a a filesystem path. In this case (with no authority):

  file:///C:/windows/path

"/C:/windows/path" is the "path", but it is obviously not a filesystem path.

I don't mind which way we fix it, but I'd be glad if we can avoid
snarky and erroneous "Windows does this wrong" comments in the code
while doing it...
