Isn't better to just inspect the default? It would look like:

Suggested change

	* `--var...` (`atom`) - a var [default: `foo, bar`]
	* `--var...` (`atom`) - a var [default: `[:foo, :bar]`]

[mateochr]

yes but the strings would look like this

if you are ok with it i can apply it

[mateochr]

that's the test tho, the normal doc would look ok?

[pnezis]

Exactly this is the escaped string, mix help, and mix docs will look fine

[mateochr]

did you mean to do inspect only when default is list or not?

[pnezis]

we can always inspect, #{inspect(...)}
