If your mail client cannot be kept from mangling spaces into unbreakable
spaces, you might want to think about attaching program files.

Try this.

% ----------------------------------------
highlight =
#(define-music-function (mus)
  (ly:music?)
  (make-relative (mus) mus
   #{
     <<
       $mus
       \makeClusters $mus
     >>
   #}))

\new Staff {
  \highlight { c'8 d' e' f' g' a' b' c'' }
  \relative c' {
    c1  \highlight { c8 d e f g f e d }
    c1  \highlight { c8 d e f g a b c }
    c1  \highlight { f,4 e d c }
    c1
  }
}
% ----------------------------------------
