Log message:
        Fix overprinting issue with Acrobat reader.
        
        Problem reported by Heinz-Jürgen Oertel <address@hidden>.
        
        * src/devices/gropdf/gropdf.pl (do_t, FindChar): Use ascii octal
        notation (i.e., \015) when outputting characters with value < 32. 
        This fixes a bug which affected acroread when control-M (cr) was
        embedded in a text string.
