2 * Internals of the Terminal structure, for those other modules
3 * which need to look inside it. It would be nice if this could be
4 * folded back into terminal.c in future, with an abstraction layer
5 * to handle everything that other modules need to know about it;
6 * but for the moment, this will do.
