The problem is basically the same with M-! asynchronously --
`C-u M-! echo hello &' will also bug out.

So inserting things into the current buffer asynchronously has possibly
never worked?

The issue here is that in the async case, we set up a sentinel to handle
the output, and we also erase the output buffer, and we set the mode to
shell-mode.

I think it should be able to make this work (I think it'd be nice to
have), but I think it requires some serious rewriting of this code...
