Sure, we considered that, you can find traces of that reasoning in the
audit trail, then lately I noticed the ICC and SunStudio behaviors, and
that idea appeared to me a tad too sophisticated... but if people agree,
I can return to it. Do you think that version of the warning should be
simply the default, right, simply the new behavior of -Wmissing-braces?
