I wonder could we special case `nice true` to indicate the nice return
That would lead to a problem where 'nice true' succeeds but 'nice cmd' (for whatever reason) does not. Perhaps the OS has a limit as to how many processes you can 'nice', for example. It'd be safer to add an option to avoid such race conditions. Plus, as you mention it'd be less hacky, which means it'd be more straightforward to document.
