This needs reworking now that 'pause_maybe' is a separate function, as 
the code no longer exits, it just keeps going.

One other thought. It may well be better to open /dev/tty lazily, that 
is, inside pause_maybe's 'while (true)' loop, just before the 'read' 
(assuming /dev/tty has not already been opened). That way, pr -p needn't 
unnecessarily fail when printing an empty file (where /dev/tty isn't 
needed after all).
