Run the command without using shell=True.

It mainly allow to run command in directory containing space.
(Hello, `C:\Program Files\...`)
It would also allow to work on directory containning spaces

support it :/

- Run the command without shell=True
- The command must be a list instead of a string.
- All options must also be a list (or an iterable).
