The ANSI control sequences are disabled by default, but they are used
if the command is invoked as "sedit" instead of "edit".

When the command is invoked as "sedit" the scrolling problem is gone.

I guess this more or less supports the hypothesis that the problem
could be caused by losing incoming characters due to the lack of FIFOs
in this port + the repainting performed by "edit". If this sounds
reasonable then I guess there's not much more that can be done here. I
just wanted to make suere there were no other underlying problems.

Thank you all for the feedback and help,
