>From `clang-format` version 3.7.0 and up, , there is no way to keep following format of ObjectiveC block:

  - (void)_aMethod
  {
      [self.test1 t:self w:self callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
          u = c;
      }]
  }

Regardless of the change in `.clang-format` configuration file, all parameters will be lined up so that colons will be on the same column, like following:

  - (void)_aMethod
  {
      [self.test1 t:self
                  w:self
           callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
               u = c;
           }]
  }

Considering with ObjectiveC, the first code style is cleaner & more readable for some people, I've added a config option: `ObjCDontBreakBeforeNestedBlockParam` (boolean) so that if it is enable, the first code style will be favored.
