Subject: boobytrapped dired-do-async-shell-command question

& runs the command dired-do-async-shell-command, which is an
interactive autoloaded compiled Lisp function in `dired-aux.el'.

It sometimes will ask
A command is running in the default buffer.  Use a new buffer? (yes or no)

Which is a boobytrapped question, as picking "no" will always end up in failure...

So perhaps rewrite it so one knows there is only one good choice if one
wants to proceed...
