I think it's fair for the backend to do some manipulation but there's a line that shouldn't be crossed, that is, getting in the way of things being done properly.

That's why I bring that up. Backends have to fiddle with the data in that case. JB. -- Julien BLACHE <http://www.jblache.org> <jb at jblache.org> GPG KeyID 0xF5D65169
