The direction of merging is a little bit chaotic in recent times IMHO. In good 
old CVS days we had the rule that changes from the HEAD should be pushed to 
the branches where appropriate, not the other way round. It would be good if 
we used this rule again IHMO, as it makes tracking things easier (by humans, 
at least).
