For that specific "entire content of a function" case I mentioned the
exceptions that allow returns at the beginning of a function that
check preconditions.

But I'm more referring to your initial refactoring in
https://github.com/daviddeutsch/roundcubemail/blob/cleanup-3/plugins/archive/archive.php#L17

In such cases I think a sequence of if/else if/else blocks makes more
clear for the reader that these are three distinct cases handled in
the plugin init function.
