leave +nnnn doesn't work at all

[ado at elsie.UUCP]

Before we leave the subject, here are our local changes to the "leave.c" source
as distributed with 4.1BSD.
	1.  A mildly sexist comment has been removed.
	2.  You are reminded of when you want to leave,
	    rather than of when you have to leave.
	3.  You can use a command like
		leave 1700 go to the bank
	    to get a reminder of both when to leave and why.

Lines from the current source file follow.

	static char *sccsid = "@(#)leave.c	4.1 (Berkeley) 10/1/80";

	 * Leave prompts for input and goes away if you hit return.
	 * It nags you like a mother hen.
