This is one approach I would follow.
Since this repeats I would like to put this to a scheme construct. But I
don't have sufficient knowledge. Here is my (failed) try:

%%START
\version "2.19.65"

narrator =
#(define-music-function (dim text) (integer? string?)
   #{
     s1^\markup
      \with-dimensions #'(0 . dim) #'(0 . 0)
      \override #'(line-width . dim)
      \translate #'(0 . -1.5)
      \wordwrap {  text }
   #})


\score {
  \narrator #1  "The message"
}
%%END

It looks like the parameter 'dim' can't be used in this way to build a
valid parameter to with-dimension. Is this true? How to do it correctly?

How could I pass 'dim+2' to the override of line-width?
