The latest iteration is 5703b012 which adds a pad count to the API exposed by WindowsPath. I think we need to bury that. The previous iteration with getPathForWin32Calls and getPathWithPrefixForWin32Calls was much cleaner. For the discussion it would be useful to know if test failure was due to MAX_LONG_PATH and whether the limit includes the colon and the stream name.
