Rust Version

rustc 1.50.0 (cb75ad5db 2021-02-10)

Clap Version

2.33.3

Minimal reproducible code

fn main() {
    let _ = clap::App::new("clap-version-test")
        .get_matches_safe().or_else(|error| {
            println!("'{:?}'", error);
            Err(error)
        });
}

Steps to reproduce the bug with the above code

1. cargo run -- --help
2. cargo run -- --version

Actual Behaviour

--help output:

$ cargo run -- --help
    Finished dev [unoptimized + debuginfo] target(s) in 0.03s
     Running `target\debug\clap-version.exe --help`
'Error { message: "clap-version-test \n\nUSAGE:\n    clap-version.exe\n\nFLAGS:\n    -h, --help       Prints help information\n    -V, --version    Prints version information", kind: HelpDisplayed, info: None }'

--version output:

cargo run -- --version
   Compiling clap-version v0.1.0 (D:\Users\gerard.ryan\Desktop\clap-version)
    Finished dev [unoptimized + debuginfo] target(s) in 0.62s
     Running `target\debug\clap-version.exe --version`
clap-version-test 'Error { message: "", kind: VersionDisplayed, info: None }'

Expected Behaviour

The version output behaves similarly to the help output.

cargo run -- --version
   Compiling clap-version v0.1.0 (D:\Users\gerard.ryan\Desktop\clap-version)
    Finished dev [unoptimized + debuginfo] target(s) in 0.62s
     Running `target\debug\clap-version.exe --version`
'Error { message: "clap-version-test ", kind: VersionDisplayed, info: None }'

Thanks for reporting! This has already been fixed by #1602. But we are not maintaining v2 branch anymore. You can switch to v3 or current master.
