I don't see why. I'm not asking for buffering across multiple calls to
the built-in printf but for non-line buffering *within* the processing
of one printf.
printf 'foo\nbar\n' # One write(2) preferred, not the current two.
printf foo # One write(1),
printf bar # the second write(1).
The stdio buffer should always be flushed at the end of each printf
command, to do otherwise would break too many things and be
non-sensical. It also wouldn't match the behaviour of calling the
/usr/bin printf.
Cheers, Ralph.
P.S. Please keep me CC'd.
