there are two issues there, one was horizontal alignment (some day i'll 
do that part otherwise in order to get rid of some hard coded 
assumptions in the engine that are difficult to deal with); i fixed that 
a week ago but didn't want push a beta just before leaving for the tug 
2015 meeting

i just uploaded a beta with a possible fix for the vertical spacing 
(grid) but i'm not sure about side effects (but as there are no side 
effects outside grid mode we can experiment)

btw, columnsets are a bit special and mostly meant for magazine like 
cases and i need to redo that one in a mkiv-ish way
