2.19.x Point and click references

[Jay Anderson]

point_and_click_2.19.ly:
=============================
\version "2.19.5"

makeScore =
#(define-void-function (parser location) ()
  (let ((score
         #{
           \score
           {
             \new Staff { \include "00.ily" }
           }
         #}))
    (add-score parser score)))

\makeScore
=============================

00.ily:
=============================
\relative c' { c4 c c c | }
=============================

When compiling the above files the point-and-click links do not point
to the '00.ily' file. Instead they all point to the final line of
'point_and_click_2.19.ly'. In 2.18 this worked correctly. it's also
worth noting that if you introduce an error to 00.ily the errors
reported do use the correct filename and line number.
