Example

#!/usr/bin/env node

const program = require('commander');

program
  .version('0.0.1')
  .description('Fake package manager')
  .command('install [name]', 'install one or more packages').alias('i');

program.parse(process.argv);

When running the built-in help command on the alias (pm help i), this happens:

Expected Behavior

The alias gets resolved to install, and the information is read from pm-install

Actual Behavior

The command attempts to read pm-i and fails, as it does not exist.
