Many thanks for sharing your knowledge! That looks to me a good
reason. I did this comment because at some point I received this
comment. I try to mark this kind of things as nitpicks because
sometimes there are differences between maintainers. E.g: some
maintainers prefer 'if (something == NULL)', others 'if (!something)';
others are fine using goto even there is nothing to unwind, other
prefer plain returns, etc.

Matti, I don't want to beat about the bush with these nitpicks. It is
not my intention. So I'd say, do what the maintainer wants :)

Dmitry, I really appreciate this kind of comments, especially when
there is a justification, so I can learn more and more to do better
patches.

Thanks,
  Enric
