automatic indentation of long instrument names?

[Patrick Schmidt]

Hey all,

in previews long instrument names seem to be indented automatically (see 
preview.png) whereas on the first full page of the same score they get lost in 
the left margin (see page1.png). Is there an option for the automatic 
calculation of the level of indentation in relation to the length of instrument 
names?

Thanks for any hint!

P.S.: I know I could use centered multi-line instrument names in combination 
with the \paper variable 'indent' but I'm looking for an "automated" solution...
