Bug: mysterious "undefined" in the help text

[inadarei]

If you execute, following code used as the sample in Commander's documentation:

#!/usr/bin/env node

var program = require('commander');

program
  .version('0.0.1')
  .command('rmdir <dir> [otherDirs...]')
  .action(function (dir, otherDirs) {
    console.log('rmdir %s', dir);
    if (otherDirs) {
      otherDirs.forEach(function (oDir) {
        console.log('rmdir %s', oDir);
      });
    }
  });

program.parse(process.argv);  

You will get mysterious "undefined" in the auto-generated help:

./commandertest -h

  Usage: commandertest [options] [command]


  Commands:

    rmdir <dir> [otherDirs...]  undefined

  Options:

    -h, --help     output usage information
    -V, --version  output the version number

Yep. Thank you, I will check it later.

missing description?

The latest release on npm still shows "undefined". Where was this bug fixed?

[zhiyelee]

@inadarei Haven't released a new version. Will release later.
