Starting a new staff in the same line

[Till Rettig]

Hi all,
a user at lilypondforum.de asked how to stop a staff group and start a 
new one after a short white space with a new system start delimiter 
bracket. I couldn't really help, I pointed to the \startStaff and 
\stopStaff commands, but they won't produce the starting bracket.
Also when making a new staff the first one gets continued and the second 
one aligned vertically under it.
As a workaround I also gave the incipit workaround that is putting the 
score in the instrument name engraver. But this is not really working 
with staff groups: the vertical alignment is bad. And he also has 
"incipits" longer than one line so I don't know how they would behave -- 
I guess this is not possible.

There is probably an easy solution, who knows it?

Greetings
