I use Vim as my editor, for both my own user and root. Strangely enough, 
if I use vi (by passing a different value for $EDITOR), it works.

# EDITOR=/usr/bin/vi vipw

If I query the return status of vim though on the successful 
modification of a file, I get 0. So I don't know why it doesn't work 
with vipw.
