I don't see it hard-coded in any context such as this.

I think the regexp against which buffer names are matched in
comint-make-newly-written-buffer-visible should be customizable, with
"*Async Shell Command*" being (in) the default value.

And another question: where's the user option to turn this feature on
or off (including the default being off)?

Thanks.
