Actually, you are right. If I run the shell in a real terminal emulator (e.g. gnome-terminal), the output is always OK. The problem only appears when I run my shells on M-x term (or multi-term) in Emacs. The odd thing is that, as I reported on the email starting this thread, the problem with the output only happens when I *switch* shells, and only with Option (2), and not with Option (1) (see my original email).
