/// This technique doesn't work in all cases on Windows. In particular, a
/// directory symlink such as `C:\Documents and Settings` may not grant any
/// access other than what is needed to resolve the symlink, so `open_parent`'s
/// technique of returning a relative path of `.` from that point doesn't work,
/// because opening `.` within such a directory is denied. Consequently, we use
/// a different implementation on Windows.
