fix: teach mingle '-?' on macOS and Windows

This is the equivalent of b4925c87f1e28a1bc66d111ef046e4e083db8c5b and friends,
but for mingle. It was not previously detected that this problem also affects
mingle because it is not currently built on macOS or Windows in CI. This will be
improved in future.
