requiredOption make --help invalid

[456wyc]

when i set requiredOption on program, the --help will noneffective:

const program = new commander.Command()
program.version('0.0.1')
program
  .requiredOption('-d, --dir <path>', 'dir path')
  .option('-t, --timeout <number>', 'timeout')

when use -h, will get a error, but not the help info:

$ ./app.js -h
error: required option '-d, --dir <path>' not specified

Try updating to Commander v4.0.1, which fixes that issue (#1089 #1091).
