However, this would break piping, which is a rather more important
part of the Unix Way :-).  In particular: diff, log, status, annotate,
cat, all automate commands (and _especially_ automate stdio), ... all
expect their stdout stream to pristine of random chatter.

If you want to include the information into automate stdio's stdout
stream, you need to multiplex it in somehow, and I don't have any
particular opinion on what the best way would be to write such code.
I'm sort of surprised you even want it :-).
