#386 C# `foreach` + cast produces incorrect unpadding.

[Jon Frisby]

When enabling unpad-paren, this:

public class Foo {
  public void foo() {
    foreach(object item in (IEnumerable)things)
      DoStuff(item);
  }
}

... will be formatted to this:

public class Foo {
  public void foo() {
    foreach(object item in(IEnumerable)things)
      DoStuff(item);
  }
}

Fixed.
