Fix [3118489] for Windows only: NUL in filenames. This allows various characters to be used in win32 filenames which are normally invalid, as described here: [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars]. The Cygwin shell can handle those same filenames as well. In other shells (cmd.exe/mSys) or on the Windows desktop the filenames will look strange, but that's all.
