Fix for http://dev.ckeditor.com/ticket/9586

This Github thing is still more complex than I expected, let's hope that this is the final step

Thanks Alfonso for this patch :). Small advice for the future - it's better to open pull requests for specific branch, not master. Then you'll be able to e.g. open multiple pull requests. You can also follow our naming convention, so in this case branch would be named t/9586 (ticket branch).

Thank you.
I have a lot to learn about Git so any advice (little by little) is welcome. And now that I've started working on it I might be able to understand things that previously were just confusing new concepts.
I've created a new pull following (or at least I tried) your advice, and I guess that branches here means something much simpler that what I was used to and that I was afraid to do for simple things like these simple patches.

Yep - if you haven't got Git experience before, then you'll have a lot of fun discovering how many times it's better than the old SVN :).

You've done the new pull request exactly like it should be done. Thanks :).
