Leaf nodes declare that they are dependencies of themselves

[timoxley]

mkdir read-installed-bug && cd read-installed-bug
npm init -f && npm install read-installed --save

index.js

var depth = parseInt(process.argv[2], 10) || 0

read(process.cwd(), {depth: depth, dev: false}, function(err, installed) {
  if (err) throw err
  console.log(inspect(installed, {colors: true, depth: 30}))
})

Now run this with node index.js 0 to print depth 0 and you should get something like the output at the bottom of this issue.

Note that read-installed is reporting that it is a dependency of itself:

{
  name: 'read-installed-bug',
  …
  dependencies: {
     'read-installed': {
        name: 'read-installed',
        …
        dependencies: {
          'read-installed': [Circular]
        }
      }
   }
}

If you adjust the depth (node index.js 1, node index.js 2) this same pattern occurs in all dependencies at the maximum depth.

Is this somehow a feature?
