    Log Message:
    Prevent heap corruption by bounds-checking writes to opt[]Since we are now free()ing the opt[] items in bail(), I've seen heapcorruption core dumps after navigating the SCFG menus with some longconfiguration items (e.g. timed events with max-length command-lines).This heap corruption has been present for a long, long time, but notdetected since we weren't free()ing these heap-allocated items.Increasing MAX_OPLN would have been a mitigation for this issue, butusing snprintf(opt[n],MAX_OPLN,...) is the better fix.
