I'd like to look at fixing 766. Could someone suggest the best way to go about this, please? One option would seem to be to calculate the length of the text of the instrument names, and set the indent on the score equal to that plus a bit. Is this the best way? It seems to me that a system based more on the way the other system grobs avoid each other would be better, but i don't know whether that's practical or even really better.
