Yes, you're right, I tried that with the old copy_messages that worked a
bit different, that one returned a boolean.

The new functions could be made to return something, I guess the best
would be to return true when all the copying was successful.  See the
new copy_messages() copies messages from different accounts into a
specific mailbox, and thus some of those messages might get copied fine,
but some of the servers that have those messages might fail for some
reason.

You could change the set.lua like this:

	function Set.copy_messages(self, dest)
	    _check_required(dest, 'table')

	    return r = true
	    for mbox in pairs(_extract_mailboxes(self)) do
		if not mbox.copy_messages(mbox, dest, self) then r = false end
	    end
	    return r
	end

Or count successful and unsuccessful copies from different source
mailboxes, etc. but in your case this isn't necessary since you have
only one.

I guess I should add something like this to the next release...
