I know there are other ways to do this. I've been using them :)
Splitting output being tee's main purpose, adding the ability to make
the destination stderr seemed useful.
As I understood, -p sends error information about the stream to stderr,
and this would conflict. If I misunderstood, that simplifies the patch
somewhat!

Why negate -p exactly?
How common is the need for this? I've never needed it I think.
Have you an exact use case.
You could do this in bash/ksh like:
seq 10 | tee >(cat 1>&2)
You could do this on most Unix systems:
seq 10 | tee /dev/fd/2
Would that suffice?
thanks,
