Actually, it turns out the opposite is true: Timing_translator must come first, 
or else the barring is messed up.

Can anyone explain to me what's going on here, and why the comments in IR 
appear to suggest the opposite of what's actually happening?
If Default_bar_line_engraver creates a variable read by Timing_translator, 
shouldn't it require that order (i.e., DBLE then TT)?

Thanks,
Kieren.
