.. as was the order for -v, as vda pointed out.
ok, let me try to trick you into fixing this one.. :)

Go to http://busybox.net/cgi-bin/viewcvs.cgi/trunk/busybox/editors
select "awk.c" and the ndiff to "previous 17972".

Look at the diff.
Implement the same for -f.
Recompile, test. Repeat until it works fine for each and all normal and
obscure methods you can imagine.
