I tried this example with the changePitch.ly you cited in a different message 
in this thread, but got a parse error.  But I think you will find that 
\resetRelativeOctave does what you seem to be looking for with your 
hypothetical \setOctave command.  Note that you don’t need the first 
\resetRelativeOctave (or \setOctave) command in each of the relative blocks in 
your example, because the \relative command itself does that.

resetRelativeOctave has been around since at least LilyPond 2.16.2.  It is 
documented with a one-line description in Appendix A (Music Functions) of the 
NR.  I wonder if anyone else uses it.  The Lilypond-user archive contains some 
dozen references to it.
