What I was trying to get at was that it wouldn't be necessary to use
the 'automatic backup' feature of -i if 'overwriting' (aka
'destroying') the input file hadn't been requested to begin with: In this
case, the processed data would go to stdout, immediately available for
interactive inspection, and could be redirected to some other file if
so desired at the user's discretion.

'Incantation' is IMO a very unfortunate choice for describing this. It
is a sequence of instructions with exactly defined meaning which
causes a machine to perform a specific function. That's a completely
mundane thing with absolutely no 'magic' of any kind involved (except
insofar 'any sufficiently advanced technology is indistinguishable
fomr magic' [as seen by someone who doesn't understand any of it],).

Hmm ... why would I?
