But it did happed when you did not suspend the fg'ed job, even with your
patch, right?

Still I think zsh is right here, and it is an emacs bug. The problem is
emacs leaves the tty setting in a wrong state when it exits. I do not
know how zsh can help here. Note that ksh does the same, even worse,
since after this the ksh line editor becomes unusable, and I had to kill
ksh from an other terminal.
