Note that -e (extra-vars) switch can be given multiple times.

SUMMARY

It's not evident from the cli switch help text, whether the "-e"/"--extra-vars" option can be used multiple times. The proposed patch makes it explicit.

we should generalize this for all options with action="append

Do you think appending that phrase to every help text for every option that is action="append" would be the way to go?

If the answer is yes, then I think the most DRY way to implement it would be to wrap runas_group.add_argument and to output that text if action="append". Increases complexity though, code becomes less readable.

[sivel]

I think overriding add_argument is the best we can do. We'll need to subclass argparse.ArgumentParser, override add_argument, extend help, when action='append' or when action=PrependListAction and then call super.add_argument. Much of the argparse API is private, so we don't have a lot of choice on what we can poke at.

We also use argparse.ArgumentParser about 11 times in lib/ansible/cli and all use cases will need to be switched.

Our new class should live in lib/ansible/cli/arguments/option_helpers.py
