System: NetBSD zorkmid.mit.edu 1.4.1 NetBSD 1.4.1 (ZORKMID) #59: Wed Mar 8 02:08:10 EST 2000 jhawk@zorkmid.mit.edu:/usr/src/sys/arch/i386/compile/ZORKMID i386


>Description:
	ddb sometimes prints two newlines if it tries to write to
	the 80th column of the screen. This is evident in some stack
	traces.
>How-To-Repeat:
	Use 't' a lot. Sorry, still no serial console and the inclination
	to write down these cases longhand and transcribe them is not
	present.
>Fix:
