I think the following code does it, but putting the music inside a  
function is probably not a good idea. Maybe some scheme specialist can  
help you better, I'm surpassed beyond that...

%-------------------------------------------------------------------

\version "2.12.3"

repeatMark =
#(define-music-function
     (parser location volte visible)
     (number? boolean?)
     (if visible
   #{
     \once \override Score.RehearsalMark #'break-visibility =
     #begin-of-line-invisible
     \once \override Score.RehearsalMark #'self-alignment-X = #RIGHT
     \once \override Score.RehearsalMark #'font-size = #0
     \mark \markup $(string-join (list "repeat" (number->string volte)
     "times"))
   #}
   #{ #}
   ))


totito =
#(define-music-function
     (parser location visible)
     (boolean?)
#{
        \relative c'' {
                \mark \default
                d1
                \mark \default
                \repeat volta 3 {
                        c b
                }
                \repeatMark #3 #$visible
                a
                \mark \default
                g
        }
#})


\score {
  \totito ##t
}


\score {
  \unfoldRepeats {
    \totito ##f
  }
}
