Subject:	vipw fails to work if the shell is anything other than empty
Description:
	If you have a root passwd entry with a shell of /bin/csh
	vipw will always think that you have mangled the passwd file.

	Try changing the shell from
		root:lkjdfljsd:0:1:Root user:\0
	to
		root:lkjdfljsd:0:1:Root user:/bin/sh
	or
		root:lkjdfljsd:0:1:Root user:/bin/csh

	vipw will complain---
Fix:
	change the strncmp, to use the length of the complare!
	diff follows
