Groovy syntax highlighting and quoted method names

Hi there, when using Groovy and quoted method names, it looks like two or more words at the beginning, followed by parenthesis breaks the syntax highlighting:

``` groovy
def "Those () or () () and neither (x) breaks a quoted method name"() {
  expect: true
}

def "Word and () however breaks a quoted method name"() {
  expect: true
}
```
