> When the flag package sees -h or -help, and those flags are not defined, it now prints a usage message. If the FlagSet was created with ExitOnError, FlagSet.Parse would then exit with a status of 2. In this release, the exit status for -h or -help has been changed to 0. This is nice. I basically only write small CLIs with Go and don't explicitly define help flags. I always wondered why it returned an exit code of 2.
