(This bug report unfortunately got no response at the time.)
This behaviour is still present in Emacs 28... but is it a bug? It's a
setting that's supposed to be used if the shell echoes the inputs, and
you're not supposed to use it if that's not the case.
Recipe to reproduce:
emacs -Q -f shell
M-: (setq comint-process-echoes t)
sleep 10
I'm leaning towards this working as intended. Any opinions?
