Nice! I do love really elegant solutions. :)
In the OP’s case, I think only the final bar is desired, so
%%%
\new ChoirStaff <<
\new Staff
\relative c'' {
\time 4/4
c4 d e f c d e f c d e f \bar "|."
}
\new Staff
\relative c' {
g4 a b c g a b c g a b c \bar "|."
}
>>
\layout {
\context {
\ChoirStaff
\consists Span_bar_engraver
\override BarLine.allow-span-bar =
#(lambda (grob)
(member (ly:grob-property grob 'glyph) '("|.")))
}
}
%%%
should do it [though, of course, your original snippet shows how to extend the
inclusion set, in case the OP wants to].
Well done!
Kieren.
