New issue 3421 by address@hidden: Percent signs in ghostscript output  
files should be duplicated
http://code.google.com/p/lilypond/issues/detail?id=3421

Reported by Pavel Roskin:

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.

Percent signs in the input files (after -f) should not be duplicated.
