Did the "if" statement immediately afterwards just look like error
checking? It's not:

    message = notmuch_database_find_message (notmuch, message_id);
    if (message)
	return talloc_steal (notmuch, message);

That's "if there's a message is in the database with this message-id,
return it straight away".

Or am I looking at the wrong bit of code?
