thank you -- i thought maybe i was the only one in the dark, and i
thought i knew more about vi than the average bear.  ":wn" seems
to be a vim thing:

    :help wn
    ....  {not in Vi}
    
if the goal is "small", maybe we should keep busybox vi to a traditional
subset...  it's so imperfect, why try to embellish it?
