sure.  there are countless little shortcuts we could add.  ":wq"
has been part of vi for over 25 years.  ":wn" is much more
recent.  that being said, i don't really care about that one -- i
don't use it, i don't do that much editing in busybox vi because
its so crippled, but that feature also won't cost that much space.

what i wrote didn't come out very well.  what i meant was, the vi
in busybox is so broken (no undo, no named marks, no regexps,
etc, etc), why bother adding little tiny things like ":wn".  the
big omissions are far more annoying than the little ones.
