That can't be right, can it?
I would have thought it would be

foo | 2>&1 bar

The first example would be evaluated the same as mentioned before. stderr 
becomes a copy of stdout, and then you redirect stdout. That won't affect stderr.

But I might be totally wrong here. I don't use sh myself, so I'm no expert... 
When it gets too complicated, I change to tcsh instead, in which I have a better 
understanding how things happen...
