addbib has the another problem yet in spite of the fix of Mr. Plotnick.
And so, I post it with his changes.

-----------------------------------------------------------------------
Subject: /usr/bin/addbib
Index: /usr/src/usr.bin/refer/addbib.c in 4.2BSD

Description:
	After fgets(line,...) is called, and the content of "line" is used,
	it is not cleared, when we type contl-d.

Repeated-By:
	%addbib test
	Instructions? y
	Author: contl-d

	or
	%addbib test
	...
	Journal: kaist
	Volume: contl-d

	etc...

Fix:
