Sergey,
Having _bash_ force pipes to be text mode seems to me to be "incorrect".
I would think that the user would prefer a binary mode, so that it does
not matter what is input and the output matches. Is there something
wrong with this idea? Are there implementation issues, perhaps?
Thanks,

You're wrong. B19 _bash_ forces pipes to be text mode. Try the same in
ash and feel the difference.
