Would be nice to see how to do it using display-buffer-alist. From my
understanding and as Stefan suggested, the best thing to do is not to
call display buffer if the intention is not to display it.

Yes I agree but let's get the count of errors right first.

I mean the 'compilation-message' property. In my second patch, the count
is based on each compilation-message properties inserted but it is
removed in, for example, these lines:

        Grep started at Wed Feb  6 09:11:06
        Grep finished (matches found) at Wed Feb  6 09:11:06

Here is the latest patches in one diff:

The total error count is still incorrect because (compilation-next-error
-1 nil (point-max)) doesn't find me the last real error but:

        Grep finished (matches found) at Wed Feb  6 09:11:06
