That would fix the problem of multiple notes per insn (as we wanted to do

That's wrong though and wreaks havoc during reload, e.g.:

Ok, thanks for working on this.
Installed, do you want this for 4.6/4.5?
If yes, please give it at least a couple of weeks on the trunk.
It's fine by me but yes, let's give it time to bake.
