New issue 2444 by address@hidden: special characters in output-suffix  
should not be translated
http://code.google.com/p/lilypond/issues/detail?id=2444

the code below produces 1 output file instead of 4:

\paper { output-filename = "output" }
\book { \paper { output-suffix = "suffix$" } { c } }
\book { \paper { output-suffix = "suffix_" } { c } }
\book { \paper { output-suffix = "suffix," } { c } }
\book { \paper { output-suffix = "suffix!" } { c } }
\version "2.15.34"

obviously the special characters are translated to underscores and then the  
previously created file is overwritten.

with special characters in *output-filename* this does not happen.
