I'd not mix \repeat volta ... and \alternative ... with manual repeat settings.

You can define it yourself, though

how about:
\version "2.18.0"
\defineBarLine ".|:-|." #'("|." ".|:" "|.")
%% needed to allow the "volta-hook" mid-line:
#(allow-volta-hook ".|:-|.")
music = \relative c' {
\key c \major
\time 4/4
\bar ".|:"
\set Score.repeatCommands = #'(start-repeat)
e4. e8 f4. f8
\set Score.repeatCommands = #'((volta "1."))
g4. g8 a4. a8
\set Score.repeatCommands = #'((volta #f) (volta "2. --1,2") end-repeat)
b4. b8 c4. c8
\bar ".|:-|."
\set Score.repeatCommands = #'((volta #f))
\break
%% not changed:
\repeat volta 2 {
e4. e8 f4. f8
\set Score.repeatCommands = #'((volta "1."))
g4. g8 f4.f8
\set Score.repeatCommands = #'((volta #f))
}
}% end relative
\score {
\new Staff { \music }
}
