Autocompletion now completes to the last matching character

[jeff-1amstudios]

if there are multiple matching commands, the last matching character is not displayed when hitting [tab]. In the below example, typing 'comm[tab]' autocompletes to 'comman' instead of 'command'.

var vorpal = require('vorpal')();
vorpal.command('command')
  .action(function (args, cb) {
    this.log('hello');
    cb();
  });

vorpal.command('command2')
  .action(function(args, cb) {
        this.log('hello world');
        cb();
  });

vorpal
  .show();
