Minor error in the trunk, I think. I only noticed because I
did a fresh clone on a new machine.

There are two new features in trunk. One will probably stay, the other
I do not know:
1) Before you could do
db.define_table('person',Field('name'),format='%(name)s')
db.define_table('dog',Field('name'),Field('owner',db.dog))
now you can also have things like
format=lambda person: person.name.capitalize()
or any other function of a person to represent it.
2) You can have
db.dog.owner.requires=IS_IN_DB(db,db.person,'%(names)s',
_and=IS_NOT_IN_DB
(db,db.dog.owner))
The novelty is in the _and.
The problem is that the exclusion is only used in validation, not when
creating the dropdown for IS_IN_DB. The reason is not is that it would
require looking two tables (the referee and the refrences). This could
be done with a JOIN in RDBs but it could not be done efficiently in
NoDBs
Any advice is appreciated.
