Rather too late to be of help to the OP, but a simple work-around using the 
usual \hideNotes trick is to define \vrest (think "vocal rest") like this

vrest = << 
  \once \hideNotes b 
  \new Voice \absolute b'\rest
>> 

and use it instead of the normal rest.  You then need to also add a 
corresponding \skip 1 (or "" ) in the lyrics to step over them.  So Peter's 
faulty example becomes:

\version "2.18"

vrest = << 
  \once \hideNotes b 
  \new Voice \absolute b'\rest
>> 

\score {
  <<
    \new Staff {
      \time 2/4
      \new Voice = "melody" {
        \relative c'' {
          a4 a a a
          \repeat volta 2 { b4 b }
          \alternative { { \vrest b } { \vrest c } }
        }
      }
    }
    \new Lyrics {
      \lyricsto "melody" {
        Not re -- peat -- ed.
        \repeat volta 2 { Re -- peat }
        \alternative { { "" twice. } { "" twice. } }
      }
    }
  >>
}
