Made more improvements to the "help" command/flag and added some tests. Does it look good to you?

It does. With that test rework we could addValidation func to this to check early if the file exists or is what it should be. Not sure if this something we want to add or not though.

I've also been thinking about adding a dedicatedconfig subcommand which would all end user to dump either the currently loaded config or one that would get loaded on init, which potentially would allow later addition ofconfig migrate between releases and would negate the need forDefault Config section. But that's for a different time, with it's own proposal and as companion to settings rework so just throwing it out there.

IMO the "DEFAULT CONFIGURATION:" section is just a legacy design that we don't want to break (at the moment it is the only approach to see where the config file is, for example: in docker, there is a shell wrapper)

As long as there is no breaking, we can still keep "DEFAULT CONFIGURATION:" section for some time, until we would have some better designs.
