Preliminary patch by Rajagopalasarma Jayakrishnan.
Issue #13772: Restored directory detection of targets in `os.symlink` on Windows, which was temporarily removed in Python 3.2.3 due to an incomplete implementation. The implementation now works even if the symlink is created in a location other than the current directory.
Use simple call to os.symlink for broken link (intended for previous commit)
