No, I meant the entire change, including your other patch. I probably
should have written my reply to the message you quote.

Unless we get some strong objections, I think we can leave the extra
newlines in GCL. I hope we'll get gray streams in some future version of
GCL. We could normalize GCL then.

I was thinking of tty-io as more of a unified interface to io streams.
In that sense, I'd like to see it built in. Also, I think we would want
to have the code compiled. (I haven't tested to see if it makes any
practical difference.)

I really don't think encouraging customization at that level is a good
idea.
