Potential regression on global args

Affected Version of clap

clap 2.26.2

Expected Behavior Summary

Using a YAML definition with an arg named quiet, defined as global I'm expecting to be able to use it in any subcommands.

Actual Behavior Summary

The quiet flag are only usable on default command, but disapear in subcommands.

Steps to Reproduce the issue

Here's the yaml

name: Test cli
version: "1.0"
args:
    - quiet:
        short: q
        help: Display only needed output
        global: true
subcommands:
    - auth:
        about: Authenticate command

main.rs

fn main() {
    let yaml = load_yaml!("cli.yml");
    let app = App::from_yaml(yaml);

    let matches = app.get_matches();

    println!("quiet: {:?}", matches.is_present("quiet"));
    println!("quiet_o: {:?}", matches.occurrences_of("quiet"));
}

Debug output

$ ./target/debug/cli
quiet: false
quiet_o: 0

$ ./target/debug/cli -q
quiet: true
quiet_o: 1

$ ./target/debug/cli -q auth
quiet: true
quiet_o: 1

$ ./target/debug/cli auth -q
quiet: false
quiet_o: 0

Thanks for filing this! I'll add it to the list as it might be related to #978 and the associated PR #1060

[kbknapp]

@Freyskeyd could you test this with the current master branch and see if it's fixed? #1070 just merged which may have helped. If not I can look into it.

[Freyskeyd]

@kbknapp I will try it as soon as I can :)
