Ugly: right bound of ‘instrument name area’

[Simon Albrecht]

Hello,

I’ve noticed that in aligning instrument names, different widths of 
SystemStart* grobs are not taken into account, which yields unpleasant 
gaps. Rather, the upper instrument name in the attached example should 
cling closer to the SystemStartDelimiter, such as the lower one clings 
to the lower one clings to the bracket.
This will not normally (with center- or left-aligned instrument names) 
make a relevant difference, but with right-aligned instrument names it does.

Yours, Simon
