A question about scanf

K&R is a tutorial, not a reference manual.  %[ has been in scanf since
scanf was first released to the world.  At first glance (I haven't done
a word-by-word comparison), the 4.1 scanf manual page looks identical
to the V7 one.  Amazingly, it looks like Berkeley hasn't messed with
("improved") scanf.
