@brenol Thanks for your contribution! This is a feature I wanted but hadn't gotten around to.

I could confirm to specify as many as needed by repeating the flag.

❯ go run main.go -H "foo:bar" -H "Bar:Foo" -H "foo:bar2" --debug http://host.xz
"header" http.Header{
  "foo": []string{
    "bar",
    "bar2",
  },
  "Bar": []string{
    "Foo",
  },
}
