How to adjust the Y-offset of volta spanners?
I have a first ending at the end of a line, which is nicely spaced (vertically). The second ending is at the beginning of the next line, and the right end of the spanner is above a rehearsal letter (/mark /default). There is more space than necessary between the rehearsal mark and the second ending volta spanner, and indeed, more than necessary under the entire second ending spanner. How might I adjust the Y-offset of the second ending volta spanner while leaving the first ending volta Y-offset unchanged? Early attempts have included: \once \override Score.VoltaBracketSpanner #'Y-extent = #'(0 . 0) \once \override Score.VoltaBracketSpanner #'no-alignment = ##t \once \override Score.VoltaBracketSpanner #'Y-offset = #10 \once \override Score.VoltaBracketSpanner #'extra-offset = #'( 0 . 50 ) placed either at the beginning of the second ending, or at the end of the first alternative, but nothing seems to budge the volta spanner. Is it possible to control the Y-offset of two volta spanners independently, and if so, how? Thank you!

The height of the spanner doesn't appear to be responsive to 'Y-offset. It
will move if you override 'padding, but this ordinarily will affect both
pieces of the spanner (first and second endings) unless you use a function
on the model of
http://www.lilypond.org/doc/v2.15/Documentation/extending/difficult-tweaks
Try this:
\version 2.15.37
#(define (my-callback arg)
(lambda (grob)
(let* ((orig (ly:grob-original grob))
(siblings (if (ly:grob? orig)
(ly:spanner-broken-into orig) '() )))
(if (and (= (length siblings) 2)
(eq? (car (last-pair siblings)) grob))
arg
\relative c'' {
\override Score.VoltaBracketSpanner #'padding = #(my-callback 3)
\repeat volta 2 {
\repeat unfold 6 { c4 d e f | } }
\alternative {
{ c2 e | }
{ f2 g | f g | }
}
}
\layout {
ragged-right = ##t
}
You can change the number in the override to apply a different value to the
padding affecting the second ending.
Hope this helps!

\relative c'' {
\repeat volta 2 {
\repeat unfold 12 { c4 }
}
\alternative {
{
\repeat unfold 12 { c4 }
}
{
\once \override Score.VoltaBracket #'extra-offset = #'(0 . -1)
\repeat unfold 12 { c4 }
}
}
}
