I'm probably confused: if shell-mode does beep, then why do you need
any changes?  Just be sure to have the "echo bell" at the end of your
command, and it will beep, right?

Before we decide that you should withdraw your suggestion, I think
it's worthwhile to figure out whether there's some Emacs bug here.  If
the shell does something, but running that shell inside Emacs doesn't,
then there's a bug we had better fixed.

But, of course, if you would like to stop the discussion, I won't
insist on continuing it.

Thanks.
