with \relative and #{ #} syntax

Come to think of it, the least invasive strategy might be hybrid: one does  
not try tracking the relation between q and the preceding chord at all but  
leaves it in the input side.  \relative just throws away the existing  
contents of any q it encounters and replaces it by the chord it considers  
as the previous chord itself.  If it has no such chord available, it keeps  
the current one and outputs a warning, like the input-based q would without  
a reference.

That way, q has predictable behavior and reference point both within and  
without \relative.  Those are not the same, but given the more pathological  
cases discussed in the comments, we could not guarantee them to be the  
same, anyway.

The effort is pretty much the same as with tracking the relation to the  
previous chord: another layer of context-keeping (and/or another pass) for  
\relative.
