If `async-shell-command-display-buffer' was nil, it did not respect
`display-buffer-alist' entries with `display-buffer-no-window'.  This
behavior has been fixed.

For example, I never want to see any shell command buffers with no
output, and I also never want to see any shell command buffers named
`*shell:mpv*'.

It seems possible to me, but very unlikely, that someone was depending
on the existing behavior in some way.  I can imagine an alternate
version of this patch that instead adds a new possible value to
`async-shell-command-display-buffer', but this seems like a clear bug to
me.  I will defer to the judgement of someone more senior on this.
