Halfprall Bug

[Hans Aberg]

The server for downloading LilyPond binaries is down, so I cannot try  
it out on latest version. I can supply a PDF if you so want. The  
UTF-8 character between the { } in the halfprall and  
halfprallfontname definitions below is in both cases U+1D19D.

Source code example follows:

%{
  LilyPond 2.11.23: Halfprall Bug

Using d'\halfprallfontname, defined as below, which explicitly  
defines the font name,
causes U+1D19D MUSICAL SYMBOL ORNAMENT STROKE-3 to be raised over the  
staff lines.
Replacing by d'\halfprall, which does not call the font name  
explicitly, does not make this happen.
Nor does it happen when \halfprallfontname is used on other notes,  
like the cis in the example below.

System Mac OS X 10.4.10 with only font carrying U+1D19D Euterpe from:
  http://openfontlibrary.org/media/files/Eimai/191
installed as system font (in Library/Fonts/; "Computer" in Font Book)
