ruby 在jruby-parser中添加context-blocks示例之前和之后。

with a faked failure resulting from altering the 'no assignment to the splat' spec to purposefully fail like this:

```ruby
        it "parses a splat that should recieve no assignment" do
          parse("a,*b,c,d = 1,2,3,4", v).find_node(:multipleasgn).tap do |masgn|
            masgn.should have_static_assignments([[:a, 1], [:b, []], [:c, 2], [:d, 3]])
          end
        end
```

```
$ rake spec
