SystemStartBar on one-staff systems

[Risto Vääräniemi]

Dear All,

I'm trying to add a bar line to the beginning of a system with just one
staff. By default the line is missing but sometimes that looks a bit odd –
especially when the system starts with a bracket.
 
I think I found the recipe that should add the bar line. However, it's not
working I expected. In fact it's not working at all. :-)

I tried to modify the SystemStartBracket example provided by Reinhold
Kainhofer and added a new line to change the collapse-height of the
SystemStartBar. I wonder if this object is for creating bar lines or for
something else. Can anyone tell if there's something wrong in my example
code? The bracket appears all right but the bar line is missing.
