Python subprocess.run and argparse nargs (multi-value options) is tricky

If you have a Python program that uses argparse nargs to specify multi-value options then you need to make sure that each value is its own parameter.

import subprocess

subprocess.run(
    [
        'command',
        '--multi-option', 'value1', 'value2',
        '--anotheroption=value'
    ])

If you don't do the above, the subprocess command will complain that the option wasn't set.
