[CM] undefined functions related to MOVING-SPECTRUM

[David O'Toole]

The functions mentioned in the documentation, "moving-spectrum-amps,
moving-spectrum-phases, and moving-spectrum-freqs" appear to be
undefined. Grepping /usr/local/share/snd/*.scm doesn't show it, and
calling the functions fails with "moving-spectrum-amps: unbound
variable". MOVING-SPECTRUM actually works, though. I just can't get
the data out.
