Title: GROOVY-6593 

This commit works, but I'm always nervous about changing the grammar as there may be edge cases I haven't considered that would break existing code...

Can anyone think of any exceptions?

[From JIRA](http://jira.codehaus.org/browse/GROOVY-6593):

In Groovy, you can add carriage returns before the dot operator. For instance:

```groovy
doSomething()
.somethingElse()
.collect { ... }
```
But with the safe navigation operator or the spread operator, it does not work.

```groovy
doSomething()
?.somethingElse() // does not compile, "unexpected token ?."
?.collect { ... }
doSomething()
*.somethingElse() // does not compile, "unexpected token *."
.collect { ... }
```
