A program that does not compile kills the daemon before it binds, which is
the failure anyone starting one from Emacs will actually hit. Showing that
buffer is the difference between a message and an answer.
The prompt also offers the program last started: a restart after a quit is
the common case, and it is rarely the buffer you happen to be reading when
you decide on it. C-c C-x does the restart without the prompt at all.
