It does appear to work! The other thing about the broken snippet, though, is 
that it allowed the user to choose both the direction of octavation and the 
number of octaves. Is there any way for this kind of functionality to be added 
here? E.g.

\relative { \myoctavate #-1 { ... } }

to add notes an octave below.
