System: NetBSD digital.clock.org 5.1_STABLE NetBSD 5.1_STABLE (FLAPJACK2) #2: Wed May 18 13:17:14 PDT 2011 root@digital.clock.org:/var/obj/sys/arch/sparc64/compile/FLAPJACK2 sparc64

>Description:
	When nvi is started as "vi" and the TERM environment variable is unset,
	nvi gives a nonsense error and exits with a non-zero status. This is a
	regression from original "vi" which would revert to "ex" line editing mode
	under these circumstances.

	This is particularly annoying when attempting to use vipw(8) in single
	user mode of a freshly booted NetBSD system (when TERM is unlikely to
	be set), and is likely to be confusing to less experienced system
	administrators. It certainly violates the principle of least astonishment.

>How-To-Repeat:
	/bin/csh
	% unsetenv TERM
	% vi
	ex/vi: Error: unknown: Invalid argument
	%
