Forcing volta brackets to be closed (v2.4.2)

[Thies Albrecht]

Hi everyone!

I'm trying to get something like this:

         |--------------||--------------||---------------|
|: Notes1 | Alternative1 :| Alternative2 || Alternative3 |. Notes2...

The problem I'm facing is that the right side of the second volta 
bracket is open as soon as I'm changing the bar line after the second 
alternative to "||" using the \bar-command. This behaviour can be 
observed using either the common \repeat-command or "Score.repeatCommands".

Any hints how to force the volta brackets to be closed as either side 
are welcome. (For lilypond version see subject.)
Additionally I want the volta number of the third alternative to be set 
to "Fine".

Kind Regards,
Thies Albrecht
