"full" buffering actually uses a default or custom buffer size when you
don't specify it. 4096 or 8192 usually (yes there's a heuristic :-)).
"full" buffering is the default for binary streams, as well as for text
streams which aren't a tty. text streams which are tty default to line
(I admit full buffering is a confusing name; what could we use instead?
fixed-size buffering? chunk buffering?)
