Thanks.  I've had a brief look at term.el to see what could be causing
this -- I wondered whether it might be a window change hook or
something, but that doesn't seem to be the case.

It seems to be happening non-synchronously -- sometimes the extra
newline isn't added until half a second passes, so perhaps it's
something that happens during communication between the shell and Emacs.

I'm pretty unfamiliar with the term.el code.  Anybody know where to
start poking?
