Percent signs in ghostscript output files (i.e. those after
-sOutputFile) should be duplicated on the command line. It's not a
format string bug as I initially suspected, it's a documented feature.
http://ghostscript.com/doc/8.63/Use.htm#File_output
"Note: Since the % character is used to precede the page number format
specification, in order to represent a file name that contains a %,
double % characters must be used. For example for the file my%foo the
OutputFile string needs to be my%%foo."
As it stands now, lilypond generates a postscript file but fails to
produce a pdf if the original filename contains a percent sign.
