Repeat in the middle of a measure

[Tim Slattery]

I'm setting a song in Sacred Harp style, kind of a 19th century style.
I know about the \sacredHarpHeads directive, that works beautifully.

This piece, as many songs in this style, has a chorus that begins in
the middle of a measure. The song is in 6/8, the soprano part (for
example ) has a measure that should read c'2 repeat-symbol r8 g8. The
repeat goes to the end of the piece.

I've tried putting \repeat \volta 1{ in that spot and } at the end of
the piece. I get a thick bar line with a colon, and the corresponding
end repeat sign at the end of the piece. OK, but then there's another
begin-repeat symbol 4 measures after the one I specified and 4
measures before the end of the piece. Where did that come from?

Another question: I would like to have the repeat symbol be just four
dots vertically, one between each staff line. That's traditional for
this type of music. Looking through the manual, I don't see a way to
do that.
