as text scripts.

Allow (closed) scheme function calls as text scripts.

This allows, for example, things like

arrow = #(define-scheme-function (parser location arg) (pair?)
  #{ \markup { \line { \draw-line #arg \arrow-head #X #RIGHT ##t  } }
  #})

\score {
  \new Staff {
     c4_\arrow #'(10 . 0)
  }
}

which, as contrasted to markup commands, is more compact to use.
