[PATCH 3/5] [programs/cmd] RESEND: for /f fails to launch quoted program plus args

[Jason Edmeades]

Fixes bug#39906

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.
