I've tested this with ardour and dssi plugins, and they don't seem to respond to any of the possible queries like #type-signature or #documentation. It would be nice to have at least one program patched, (or make a program that does nothing, but responds to everything descently), so we have a test case... greetings, lieven P.S. This patch does not filter messages yet, because I first wanted to see what applications are responding to. It seems that the applications I tested don't even reply #error messages, when a query cannot be replied to.
