A truly ugly hack:

\version "2.19.81"

frontmatter =
#(define-music-function (mus) (ly:music?)
   #{
     \omit Score.Clef
     \omit Score.TimeSignature
     \stopStaff
     \hideNotes
     #mus
     \bar "|"
     \set Timing.measurePosition = #(ly:make-moment 0)
     \unHideNotes
     \startStaff
   #}
   )

backmatter =
#(define-music-function (mus) (ly:music?)
   #{
     \stopStaff
     \hideNotes
     #mus
   #}
   )


\relative c' {
  \frontmatter { <f a>4~( }
  <f a> g a b c~
  \backmatter { c) }
}

One of the many drawbacks being that the hidden music takes up space. 
(Which, funnily enough, is in fact no problem in _my_ workflow, since I 
always use Frescobaldi's auto-trim feature for copying the music 
examples into my LibreOffice documents.)
