### Summary

Writing this following #79967, which I created because I thought that I encountered a bug, but in fact I didn't know some details about how `argv` parameter works.

It would be great to have information provided to me there in the documentation in case anybody else encounter the same issues. Especially this comment was very helpful:
> precisely because you can use white space you need to separate what is not the same argument or the flag + argument are passed as a unit '--flag arg' vs '--flag' 'arg'

### Issue Type

Documentation Report

### Component Name

https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/command.py

### Ansible Version

```console
$ ansible --version
```


### Configuration

```console
# if using a version older than ansible-core 2.12 you should omit the '-t all'
$ ansible-config dump --only-changed -t all
```


### OS / Environment

Linux

### Additional Information

When the improvement is applied, it makes it more straightforward to understand how argv parameters works
