In the snippet collection, the "Repeats" section, there is one named "Shortening volta brackets". I have use for just this, since in a piece of music I need some extra space in order to put a mark immediately after the volta alternative bracket. So I tested it, and, yes, the example promised well. The method is to work with the variable voltaSpannerDuration via the the statement:
"\set Score.voltaSpannerDuration = #(ly:make-moment 2 4)"
This way you can shorten the bracket even down to one single strike:
But when I expand the system to this, hence two staves instead of one, this happens:
I'll have to look at this some more, but it seems there is a bug. Even in the single staff example, there is a warning: "cannot end volta spanner". I get this with the snippet you reference as well. Possibly there is a flaw in lily/volta-engraver.cc. And another "possibly": this might be related to what happens in your multi-staff example.
