PS2: 
And now I saw a merge conflict because of this. Please always keep in
mind that style changes are easily merged but can make the work on
actual functional changes that are harder to get merged even harder.

I suggest you make a rule of this: Please attend / take over unmerged
patches before you do style changes.
