Misaligned help text with positional arguments and numpydoc

[rezahousseini]

When using Numpydoc docstring style with multiple positional arguments the help text gets misaligned

import fire

def run(executable, argument):
    """Run.

    Parameters
    ----------
    executable :
            Executable to run
    argument :
            Positional argument to the executable

    """
    print("hello")

if __name__ == "__main__":
    fire.Fire(run)

When run with python test.py --help this code produces

INFO: Showing help with the command 'test.py -- --help'.
