the file: protocol has a long and messy history; it is now probably
impossible to use in a consistent way without breaking something.  It
works fairly well for the tail of the path, but so does an ordinary
list of path components.

In general practice, even just using a string with a slash in either
direction as the separator will work.  If that has too many corner
cases for your taste, then you should treat "file:" as undefined
behavior.
