Change output filename from <stdin>_out.csv (invalid on Windows) to stdin_out.csv

Hi, usually I use csvkit inside cygwin, and it works great.

But I have strange stdin problem. If I run the below command on my debian machine I have no problem.

curl -s "http://217.222.248.115/BdProcedimenti/consulta/tmp/ProcOpenData.csv" | csvclean -d ";" -u 3 -e Windows-1252

If I run it in cygwin instead I have: [Errno 22] invalid mode ('w') or filename: '_out.csv'

I know it's not a csvkit problem but something related on environment settings, but I do not know where to start.

Thank you
