Handling 404's

[jrf0110]

Currently, if you try to get a repo that can't be found, you get this:

{ [Error: Not Found]
  domainEmitter:
   { domain:
      { domain: null,
        _events: [Object],
        _maxListeners: 10,
        members: [] },
     _events: { end: [Object], data: [Function] },
     _maxListeners: 10,
     writable: false,
     readable: true,
     paused: false,
     autoDestroy: true,
     push: [Function],
     queue: [Function],
     end: [Function],
     destroy: [Function],
     pause: [Function],
     resume: [Function] },
  domain:
   { domain: null,
     _events: { error: [Function] },
     _maxListeners: 10,
     members: [] },
  domainThrown: false }

What would you think of reporting:

Could not find repository. Did you forgot to authenticate with --auth?
