Re: 23.0.50; ^D inserted into network streams

I think this is a feature that was designed to get out of a state
where a subprocess is waiting for a line of input and the kernel won't
give it any input until it gets a whole line from Emacs.

I do not know if that problem can still occur in modern systems.

Your patch looks correct to me.  I installed it in Emacs 22.
Thanks.
