Hey hey - you did it!
I did my console switch, which *always* revealed the bug,
and it is not there any more.
I've also spent a couple hours in cooked mode programs, like my editor,
and the lines are all correct.
I'll keep at it for a few days, but for now I'm going to say it's fixed.
Please push this into the next release, and perhaps backport
if possible; for those of us in cooked line mode
it was really an inconvenient bug.
Finally, my complements to you.
I read the code in n_tty.c and I don't understand any of it.
It's way beyond me.
Nice job, and thank you.
