Ah -- as I said, I hadn't had time to study the existing code, so didn't
appreciate this.  The above was merely an idea, to stimulate the design
discussion.

Just a further thought, however;  since we are principally concerned
with draining input from a pipe, do we need to bother with processing
further stacked input files, after we reach the cleanup_and_exit()
phase in troff?

Best regards,
Keith.
