Does this work on strange Unixen?

[Kai.Grossjohann@CS.Uni-Dortmund.DE (K. )]

Given that `command' is a command which prints something to stdout
and also something to stderr, does the following work to prefix all
stdout lines with O and all stderr lines with E?

{ { command|sed 's/^/O: /' >&3;} 2>&1|sed 's/^/E: /';} 3>&1

In particular, I'm interested in AIX, IRIX, and other exotic systems.

I used the following shell script to test:

/----
| #!/bin/sh
| echo stdout1
| echo stderr 1>&2
| echo stdout2
\----

tia,
kai
