The other possibility is: `gnus-configure-posting-styles' adds all its
actions to `message-setup-hook'. Perhaps the way it's meant to work is:
g-c-p-s adds *forms* to the message-setup-hook, but those forms aren't
actually evaluated until the hook is running, at which point we should
have access to everything we need.

I would need to look more closely at it to tell if that's the case, or
if it *could* be the case, but it would be one way that this code might
once have worked.

You'd be amazed at the number of ways things can blow up!
