     * Ugly backwards compatibility. Flip any file separator
     * characters to be forward slashes. This is a nop on Unix
     * and "fixes" win32 file paths. According to RFC 2396,
     * only forward slashes may be used to represent hierarchy
     * separation in a URL but previous releases unfortunately
     * performed this "fixup" behavior in the file URL parsing code
     * rather than forcing this to be fixed in the caller of the URL
     * class where it belongs. Since backslash is an "unwise"
     * character that would normally be encoded if literally intended
     * as a non-seperator character the damage of veering away from the
     * specification is presumably limited.
