That's fine.

We want to check for two vastly different conditions: - Do we have to inspect the multi-hook directory? That decision should be based on existence. - Do we have to issue a warning? That can be based on the executable flag. (As I understand, this is just a convenience warning because we do not want the user to see a cryptic "cannot execute this thing" error or something.) I can see that you sense an inconsistency when you treat "not executable" as "does not exist". But that is just too subtle in my book, hard to explain, and not the practice that we are exercising these days. I'm more concerned about the platform differences that we would have to note in the documentation: "To have multple hooks, do X and Y and make sure the standard hook file is not executable. Oh, and by the way, if you are on Windows, you have to remove the file to make it not executable." Let's not go there. -- Hannes
