Unnice following up to myself, but...:

Actually, both issues are with readline.py, not
with Console.py itself.

...because it does no test for it whatsoever (I think).

...because it keeps .cursor(0) normally, with a .cursor(1)
only while the line-reading loop is active, and there is
no .cursor(1) at the end to restore things.

Both issues are worked around by adding an extra case:
            elif e.char == "\032":
                c.cursor(1)
                return ''
to the while 1: loop in method readline().

As I was at it, I also added rudimentary history with
up/down arrow (the class did keep a history but offered
no way to navigate in it, that I could see).  I included
both tiny fixes in the already-mentioned
    http://aleax.supereva.it/Python/cons0528.zip
(downloadable, as mentioned before, only by navigating
to this URL in your browser then clicking on the link
which displays the same URL).

I'd still be interested in better known fixes...
