Improved note-compiler: optimizing output now works properly
Previously, output was always considered as non-const, even if is was
zero and without any controller-influence, because output had always
pfactor-influence. Now, a pfactor-influenced output which is constant
zero is considered as still constant, because pfactor*0 is always 0.
