You missed missing space before '}' in your review.

As far as I'm concerned such reviews are waste of both your and my time,
no matter whom they are from and right now it's you who gave me such
review. I don't know what you wanted to show me, I don't recall myself
giving such a review ever. I will send a "fixed" version with hope that
I can finally go back to fixing real problems.
