I'd really like to see this one go in: I think it would not be hard to set
up automated dumps of the gcov output and convert them to something nice
and easy to read. For people who want to volunteer but aren't sure where
to start, or who aren't quite ready to dive into app compat work extending
the test suite is a great thing to do.

In particular it'll let us easily identify things like error codes that
may be incorrect (ie, were guessed). Given the number of times we've been
nailed by people guessing error codes for obscure situations and not
marking them as guesses, any tool that can show what we're not testing
gets a +1 in my book.

Also the patch looks small, it's mostly documentation, and minimally
invasive. I see no reason to reject it, hopefully Alexandre has just been
bogged down with the WM rewrite and the huge volume of patches going in
lately.
