Why not use \repeat volta 2 { ... } here?

You can't accumulate different repeatCommands at the same point of
time, one will override the other.
Put the settings in one list as shown below.
Or use my setRepeatCommand-function from
http://lists.gnu.org/archive/html/lilypond-user/2014-07/msg00376.html
This custom function was developed for exactly this reason: to
accumulate repeatCommands.
Additionally, because we're mid-measure and no BarLine is present,
there will be no gap between the two VoltaBrackets.
I'd insert 'end-repeat (will print bar-line-type ":|.") and make this
BarLine (and the SpanBar) transparent.
See below.

> \set Score.repeatCommands = #'((volta "2.")) c32 [e16.]
> \set Score.repeatCommands = #'((volta #f))
The VoltaBracket will not be closed, because the volta-hook isn't
allowed for bar-type "|"
This can be changed, ofcourse.

Now the code as I'd do it:
\version "2.18.0"
#(allow-volta-hook "|")
music = \relative c''' {
\key c \major
\time 2/4
\bar ".|:"
\repeat volta 2 {
\partial 8 g8
a16. [g32 a16. f32] e8 [c32 a16.]
a8 a'16. [e32 f16. e32] c32 a16.
a'16. [g32 a16. e32] c32 [e16. a,16. e'32]
c8 b b[ g']
\break
\set Score.measureLength = #(ly:make-moment 5 8)
a16. g32 a16. f32 e8
\set Score.repeatCommands = #'((volta "1."))
c32 [ a16.]
\once \hide Score.BarLine
\once \hide Score.SpanBar
\set Score.repeatCommands = #'((volta #f)(volta "2.") end-repeat)
c32 [e16.]
\set Score.repeatCommands = #'((volta #f))
\set Score.measureLength = #(ly:make-moment 4/8)
a,8 a'16. e32 f16. e32 c32 a16.
b16.[ c32 d16. e32] f32 [ a16. e16. b32]
c8 [a] a
}
\break
} % end relative
\score {
\new Staff \music
}
HTH,
Harm
P.S.
No need to send me a second private mail, with the same content.
I read the list :)
Ofcourse you can cc me.
