Now that I think about it, this has already been fixed in trunk. In trunk,
you should be able to do:
db.person._format='whatever'
without having to first delete _format. That will work for any table
attribute starting with an underscore, including the new _singular and
_plural attributes (which are used as singular and plural table labels).
