Message:

Fifteen minute hack of the day: nullable text fields. No idea if/how
this will work for anything else (though I guess it mostly should).
Almost completely untested. API may change. Use at your own risk. All
those sorts of things. :)

admin_fieldset do |fieldset|
  fieldset.text_field :something
  fieldset.nullable :text_field, :something_else
end
