Subject: [PATCH] clang-format: Don't let a leading "template <..>" lead to
 wrapped initializers.

Before:
  Constructor() : initializer(0) {}

  template <typename T>
  Constructor()
      : initializer(0) {}

After:
  Constructor() : initializer(0) {}

  template <typename T>
  Constructor() : initializer(0) {}
