These two files were missing headers. There is other work on-going to automate updating of the headers, but that likely won't crossover with this.
Don't consume literal brace as Scala pattern. Previously, leading space would let the text parser `xText` handle it correctly instead.

And do the same for the specialized variants.
Tested by a Java source file that uses lambda syntax to create
instances of generic and specialized `Function{0,1}`.
Here's how the interfaces look now:
```

Compiled from "Function1.scala"
public interface scala.Function1<T1, R> {
public abstract R apply(T1);
