Re: Tuplet bracket visibility seems to break something

[Paul Hodges]

Thanks - that sorts out a lot (and exposes another issue I'll write 
about separately!).

In my many decades of programming I always had reservations about 
"syntactic sugar" - different ways of expressing the same thing.  When 
the alternatives do not have the same behaviour at all times, they can 
be positively misleading.  In this case, || appeared to work for some 
things, but then broke when something else happened; similarly the other 
week I reported an issue with some parameters which mostly worked with 
either # or \ introducing them, but one parameter value didn't.  In this 
case, as it happens, I do normally use \\ correctly, but I had a senior 
moment this week and held the shift down when I shouldn't have.
