I think we'd be OK if we work with the "common" shells. But that would 
include zsh, whose current FAQ says the following:

  Probably the most reliable way of dealing with this is to look for
    the environment variable `$EMACS', which is set to `t' in
    Emacs' shell mode.  Putting

      [[ $EMACS = t ]] && unsetopt zle

    in your .zshrc should be sufficient.

So here it's not merely a matter of fixing zsh, it's also fixing all the 
users' .zshrc files that are following this (obsolescent) advice.

So far we've looked at three shells (bash, tcsh, zsh), and found 
compatibility issues with all three. This is not a good sign.
