+Is the new password too much like the old one? This is primarily
+controlled by one argument, <tt/difok/ which is a number of characters
+that if different between the old and new are enough to accept the new
password, this defaults to 10 or 1/2 the size of the new password
whichever is smaller.
+To avoid the lockup associated with trying to change a long and
+complicated password, <tt/difignore/ is available. This argument can
+be used to specify the minimum length a new password needs to be
