Used by the routines at START, READ_LINE, ONE_KEY_MOVES, REPEAT_LAST, RUB_OUT_LINE, NARRATE_ACTION, GET_KEY, PRINT_LITERAL, WORD_AND_END, MC_BACKSPACE, PRINT_WORD, SHOW_SCORE, NEW_LINE, DO_LOOK, DO_EXAMINE, NARRATE_LINE and LIST_HELD.
Everything printed passes through here with the character in A -- which is what makes it a good place to stop to capture exactly what a message says.
