I patched the interval-stream :untyi bug by changing the
:read-bp definition to
((:UNTYO-MARK :READ-BP) ()
;; First, if there is an unread character, discard it and back up one.
(COND (*UNRCHF*
(SETQ *UNRCHF* NIL)
(IF (ZEROP *INDEX*)
(SETQ *LINE* (LINE-PREVIOUS *LINE*) *INDEX* (LINE-LENGTH *LINE*))
(SETQ *INDEX* (1- *INDEX*)))))
(CREATE-BP *LINE* *INDEX*))
It might be cleaner to eliminate *UNRCHF* altogether.
