(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?
