I've done this, and it's working in my example the same way as it does
in demo_recvline.py. It's a much nicer environment than my original:
backspace works, arrows work, you can scroll up and down through command
But there's a problem, both in my code and in demo_recvline.py: when you
get to the bottom of the terminal it doesn't scroll. All the lines just
get pasted over each other on the bottom line of the terminal. I'm
clueless about terminal programming: generally I just know that I can
dump a bunch of text and the terminal will scroll. But now it doesn't.
Can you help me fix this?
Once I get this all working, I'll post a modified simplesshserver.py for
the benefit of others who might want a working line editing and history
for their custom protocol.
