Our copyright string is longer than JMSG_LENGTH_MAX, and this was causing a buffer overrun if output_message() was called with msg_code set to JMSG_COPYRIGHT, or if format_message() was called with msg_code set to JMSG_COPYRIGHT and with a buffer of length JMSG_LENGTH_MAX.
We can't simply increase JMSG_LENGTH_MAX, because it is part of the libjpeg API, and it is generally assumed that a buffer of this length will be passed to format_message(). Thus, the easiest solution is simply to use a shorter copyright string for JMSG_COPYRIGHT.
