Is this in CodingStyle now? Since I have noticed you are pushing for this 
quite a lot lately. And only for structure initialisation and not also for 
example for variable declarations?

I find it a matter of personal preference whether it is more pleasant to look 
at and whether it is more or less readable.

It is also worse from diff/patch point of view since it can happen in the 
future that what would be a one line change now becomes multiline.
