Split showHelpOnFail error level

[artembeep]

Is it possible to customize somehow error level for showHelpOnFail to show help only for cli notation level errors.
E.g. wrong option set provided, unknown command etc.

But same time to skip usage screen if an application level error is raised.

Thx!

I am not sure I understand. What is an example of an application level error? (Like a throw, or accessing undefined variable in own code?)

I've noticed that help is shown either when the user specifies an invalid command/option, or when an async command handler throws an error. I wonder if that's what OP is running into and trying to disable. I've opened an issue with more details about this case at #2394.
