Description
Currently "prog -help" relies on the "print usage and exit non-zero if given flag is undefined" behavior in the stdlib "flag" package.
To fix this, we can set ErrorHandling to ContinueOnError, and check the return value of Parse():- if flag.ErrHelp, os.Exit(0)
- if other non-nil error, os.Exit(2)
