wcmd: ignore start and end quotes (try 5)

[André Hentschel]

now without touching the existing code

in cmd tested with:
>set foo=bar
>set foo
bar
>set "foo=test"
>set foo
test
>set "foo"
test

strip function tested with:
wine cmd /c "net help"
wine cmd /c /s "net help"
wine cmd /k "net help"
wine cmd /k /s "net help"
wine cmd /c "net "help""
wine cmd /c /s "net "help""
wine cmd /k "net "help""
wine cmd /k /s "net "help""

and the results stay the same
