Sure, but how is that relevant?  This discussion is regarding a cosmetic 
issue.  As I see it, Time_signature_performer would not need to care as 
long as the normal Timing properties are well set.

I did say I took a quick look through the code.  Ultimately, I misread a 
comment about missing iterators as missing listeners.  I found no 
references to time-signature-event because I forgot that in C++ that 
becomes listen_time_signature.  And my fast review of 
time-signature-engraver.cc was overly focused on process_music.
