>Description:
	libedit history mechanism keeps a history of input lines.
	The number of lines in the history is set by a call to
		history (hist, H_SETSIZE, size)
	And when this is set, libedit keeps one extra line than
	was requested.

>How-To-Repeat:
	sh -E
	$ HISTSIZE=5
	$ 1
	$ 2
	$ 3
	$ 4
	$ 5
	$ 6
	$ 7
	$  (Now ^P back and see you still see 2, but not the 1, which
 	    is 6 elements of history, not 5.)
	$ HISTSIZE=0
	$ 1
	$ 2
	$  (Now ^P back and you see 2, but not 1, which is 1 element,
	    not 1!)

>Fix:

	I couldn't find it in my quick look.
