Many thanks Andreas.  I hadn't heard of col before.  It's useful but no
good for processes that require user input (such as apt).

A function; (comint-carriage-motion), and a variable;
comint-inhibit-carriage-motion, exist precisely for this purpose.

How best to apply them to buffer *Async Command Output* is something I'm
still working on.
