Damn, syntax highlighting of commit messages apparently doesn't work! Here's what it was supposed to do:

The old functionality was as follows:

```ruby
graph.v.as(:vertex).out.in.except(:vertex)
```

It is changed to:

```ruby
graph.v.as(:vertex).out.in.is_not(:vertex)
```

The good news is that now you can do this:

```ruby
graph.v.aggregate(:so_far).out.in.except(:so_far)
```

Which is important for collaborative filtering and whatnot.
