Actually, the change is not drastic: the second and third arguments are 
optional 
<http://lilypond.org/doc/v2.19/Documentation/notation/scheme-functions#index-ly_003amake_002dduration> 
and have also been so in v2.18. So these notations are fully equivalent, 
only the preference in creating \displayXX output has changed.
Same for the last argument to make-pitch.

HTH, Simon
