Isn't that what \resetRelativeOctave does? His description seems exactly 
to match my problem with Pennsylvania 6-5-0-0-0

It was an example which - obviously - predated both \resetRelativeOctave 
and \makeRelative (you did notice the "version 2.8.0" at the start?)

I couldn't remember what \resetRelativeOctave was, so I was trying to 
give him the clues he needed to find it. I did explicitly say "I think 
it's now a standard part of lilypond" (implying it wasn't when that code 
was written).

So let's give a very simple example of what I think he was trying to 
achieve ...

arpeggio = { c e g c }
\new Staff {
  \relative c' {
    \arpeggio \resetRelativeOctave c'
    \arpeggio \resetRelativeOctave c'
    \arpeggio
  }
}

Despite being in relative mode, all the arpeggios will now start on 
middle C. The OP's eXample is more complicated but as far as I can tell 
this is what he's aiming at.

Oh - and I believe

arpeggio = { \resetRelativeOctave c' c e g c }

would also work. I don't know for certain because I haven't had this 
problem since Pennsylvania.
