bug#69317: 30.0.50; RFE: not waiting for a permission to kill a dead process

[Sam Steingold]

When I hit g (recompile) in a *Compilation* buffer while the previous
compilation is not done yet, I am asked whether I want compilation
killed. If I wait for it to finish, I get the echo area look like this: 

A compilation process is running; kill it? (y or n) [Compilation finished]

It would be nice if as soon as the compilation finished, the question
automatically disappeared and the compilation restarted.

I looked at the source code, but I see not simple way to make it happen.

NB1. Of course, this requested change should also affect
`process-kill-buffer-query-function`...

NB2. compilation-always-kill is not what I want: it kills the
compilation right away. I want Emacs not to wait for my permission to
kill an already dead process.

Patches to implement that are welcome.
