3 is my favourite. It means that if I run
and I want to see exactly what the output was, I can run
./foo | hexdump -C
and get something consistent with the first run.
0 breaks the above.
1 means that if you and I both generate a file we don't necessarily get
the same file.
2 I don't like for your "prog in" vs "prog < in" reason, and likewise
"prog -o out" vs "prog > out".
I think it's important that we have some way of sending/getting binary
stuff to/from std*, though (and we need to make sure it plays nicely
