Strings() doesn't work with flags

You have to repeat the flag: -s hello -s world

According to
https://godoc.org/gopkg.in/alecthomas/kingpin.v2#FlagClause.Strings a
flag should allow the type to be a list of strings:

func (p *FlagClause) Strings() (target *[]string)

Strings accumulates string values into a slice.

Using the following code:

package main
import (
"gopkg.in/alecthomas/kingpin.v2"
"os"
)
var (
app = kingpin.New("my-app", "It does cool things!")
someStrings = app.Flag("strings", "Give me some strings baby!").Short('s').Strings()
)
func main() {
kingpin.MustParse(app.Parse(os.Args[1:]))
}

And running the test app like so: ./test -s hello world

I get the following error: test: error: unexpected world, try --help

This is the help output:

usage: my-app []

It does cool things!

Flags:
--help Show help (also see --help-long and --help-man).
-s, --strings=STRINGS
Give me some strings baby!
