Never mind, finally found the bug, for others as desperate as me, here it is:
http://bugs.mysql.com/bug.php?id=26511


I was surprised to see, though, that is was marked as "Feature request": Being new to the bug-tracker, I'm not sure what exactly that means, but my humble opinion is that it is not a feature request, but the very esence of how a composite index works: A composite index that does not use all columns, is just a simple index and has no reason at all to even exist!
