I must admit I have big troubles reading context diffs. Will it be a problem
for you to send diffs in unified format?

If I read the patch correctly, you add two lines of code? Given that
get_type_deref is defined like this:

static struct type *
get_type_deref (struct varobj *var)
{
  struct type *type;

  type = get_type (var);

  if (type != NULL && (TYPE_CODE (type) == TYPE_CODE_PTR
                       || TYPE_CODE (type) == TYPE_CODE_REF))
    type = get_target_type (type);

  return type;
}

does the code you've added ever does anything?
