When a line follows Options: declaration, options don't parse correctly

[ghost]

Description

When a non-option line comes after the Options: declaration, parsing fails in weird ways. Not only are options missing, but -h and --help are now split. This doesn't happen at try.docopt.org.

Repro

1. Start with the options shortcut example

package main

import (
	"fmt"
	"github.com/docopt/docopt-go"
)

func main() {
	usage := `Example of program which uses [options] shortcut in pattern.

Usage:
  options_shortcut_example [options] <port>
  options_shortcut_example -h | --help

Options:
  -h --help                show this help message and exit
  --version                show version and exit
  -n, --number N           use N as a number
  -t, --timeout TIMEOUT    set timeout TIMEOUT seconds
  --apply                  apply changes to database
  -q                       operate in quiet mode`

	arguments, _ := docopt.Parse(usage, nil, false, "1.0.0rc2", false)
	fmt.Println(arguments)
}

2. Modify as such

 Options:
+These are things
   -h --help                show this help message and exit

Expected Behavior

$ go run options_shortcut_example.go --help
map[<port>:<nil> --help:true --version:false --number:<nil> --timeout:<nil> --apply:false -q:false]

Actual Behavior

$ go run options_shortcut_example.go --help
map[<port>:<nil> -h:false --help:true]
