​I tried to integrate these changes with Eli's feedback, but I got stuck.

"The way recommended by Martin" involves a new minor mode,
async-shell-lazy-pop-up-mode, which I tried to avoid; Eli didn't seem to
support its addition, either.

I'm not sure what the variable async-shell-command-display-buffer is
supposed to contain. (It does not seem to be the name of the buffer to be
matched.)

I am unclear what goes in the ellipsis after "when" in the sample code
above; it seems to imply a test for whether the buffer should be displayed,
but I already handled that in my patch with the preoutput-filter function.

So, the above seems to be an alternative suggestion to Eli's, rather than a
complementary one, as I first thought.

It would be good if you experts could agree on an approach that I could
quickly implement. I'm out of my depth here as far as design goes, and
while I'm learning a bit, I'm not sure it's a good use of the total amount
of time we seem to be expending between us!
