Adding "--help" and "-h" to the plugins

[ghost]

Hi there,

what about adding "--help" and "-h" to the plugins? I'm coming from the Linux side and i recently ran "m wallpaper --help" by mistake and it changed my wallpaper to the default Sierra one.

Not so great.

What do you think about that?

I just ran this expecting a help description for wallpaper and now my wallpaper is black and Dock.app won't open, ever after reboot. Now I have no dock and can't use app switcher or spaces. No idea how to fix this on Catalina...

Not good at all.

You're right, that's a terrible experience @nanisean. I think the latest release isn't nearly as destructive for the wallpaper command, and m wallpaper -h fails safe.

I'll have a think about how to alias -h and --help as they're common
