   Yes, there is definitely a difference, except you won't see any on a U**X   
   system. The most visible difference is how end-of-line is handled. Inside   
   the program you always output '\n', in the file system this might happen   
   for text files:   
    Unix or similar: '\n' is unchanged   
    MacOS: '\n' is replaced by '\r'   
    MS Windows: '\n' is replaced by "\r\n"   
    VMS: depends on file structure, for system-compatible text files '\n' is   
     dropped, instead a record length is prepended to the line.

   You example doesn't use any problematic character. Try again with writing   
   '\n'.
