Indeed there seems to be an issue here, but:
Have you tried in your batch with a few "index"ed parameters to ipt with
your fix? I think it will break with your changes. Of course that does
not invalidate your concern. If you send me a two liner batch example
which breaks for you, I will test it.

I think #2 and #3 are leggit. Send two patches - one for #1 when you
validate and the other for #2,#3 when you validate. BTW, for the
equivalent of the latter - if you feel brave - theres a lot more of that
type in the tc code.
