This was not following the (IMO slightly silly) rule even prior my 
patch. I can for sure move my line up - but that won't give you the 
"reverse X-mas tree".

I don't have any real objections on changing the styling though - I 
don't expect this to be merged before the dependency is in rc1 - so I 
guess I will anyways need to respin this for next cycle. I can do the 
styling then.

Here I do disagree with you. Moving the array out of the function makes 
it _much_ less obvious it is not used outside this function. Reason for 
making is "static const" is to allow the data be placed in read-only 
area (thanks to Guenter who originally gave me this tip).
