cmd: for /f fails to launch quoted program plus args.

Browse source 
for /f can run a program and parse its output. The program name can
supply args and be quoted or not.  If quoted, wine fails to run the
program because internally we were adding an extra pair of
quotes. These are not needed and can be removed.
