Removing "(required)" with options that have a default value specified about cling

[devnote-dev]

I think the bigger issue here is whether required options should be allowed to have default values. With the current implementation, the Executor will just set the value of a required option to the default, so it isn't really a required option. At the moment, I'm inclined to disallow required options with defaults for the above reason, but I'm open to other views.

Alternatively, it would make sense if passing -o without a value would cause an error with the same message as when -i is missing:

I agree, and this should probably be the case for optional options with defaults.
