 ** NAME
 **   print_file_size - prints the file size to a given memory location
 **
 ** SYNOPSIS
 **   void print_file_size(char *buf, off_t file_size)
 **
 ** DESCRIPTION
 **   This function prints the given file_size in ascii decimal to buf.
 **   It assumes that buf is of at least 10 bytes long and will not
 **   use sprintf() for values less then 10.000.000.000. It will print
 **   from right to left and leading values will be initialized with
 **   a space sign.
 **
 ** RETURN VALUES
 **   Will print the given file_size to buf.
