I must confess I am not sure how much description is enough for you and what is too much. It appeared to me in the last PRs you sometimes prefer rather a minimum than a maximum of explainations to avoid useless comments about obvious things. Maybe I am wrong. 
What do you think about telling me where you want more description?
I don't want to waste your time (and mine neither) with too long texts.
Or do you really prefer the opposite? (I mean you tell me what I must remove from the texts)

Btw: I always try to be short on my answers for you because I believe you don't like to read long texts from me.
