repeat with irregular alternatives

[fiëé visuëlle]

Hello,

I'm trying to typeset a song with triple verses; the first one always  
is a bit shorter, second and third share a longer tune.

With

\repeat volta 3 {
        shared tune
}
\alternative {
        { first ending }
        { second and third ending }
}

I get (1.-2.) and (3.) alternatives, but I need (1.) and (2.-3.).
How can I achieve that?

I found the docs on "manual repeat marks" (http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Manual-repeat-marks 
), but I'd like to avoid that ugly syntax...

I generate my MIDI with \unfoldRepeats - didn't try yet if manual  
marks would work with that.
