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)
