I worried about this -- why did line-editing not cause problems, given
that it is this that EMACS=t disables.

So I tested this by doing this:

bind -x '"\C-r"':reset

which gives a warning

bash: bind: warning: line editing not enabled

It turns out that M-x shell gives a warning in emacs-25 head AND
emacs-25.0.91. So it appears that the bash  EMACS=t handling is redundant,
at least with respect to line editing. M-x shell passed --noediting
through explicit-bash-args.
