When an Arg uses .min_values(0), that arg's value(s) are effectively
optional. This is conventionaly denoted in help messages by wrapping the
arg's values in square brackets. For example:
--foo[=value]
--bar [value]
This kind of argument can be seen in the wild in many git commands; e.g.
git-status(1).
