allow event manager to handle display of execution exceptions * event-manager.h, event-manager.cc (event_manager::display_exception): New method. (interpreter_events::display_exception): New virtual method with default implementation. * error.cc (error_system::display_exception): Forward exception to event_manager::display_exception instead of diplaying directly on std::cerr stream. # HG changeset patch # User John W.
