extensions: recommend against using wrapfunction for repo methods Instead, all extensions should use the "dynamic subclass" trick: subclass repo.__class__ and then replace repo.__class__ with your new subclass. This avoids conflicts that happen when one extension uses wrapfunction and another uses subclassing to extend the same method of localrepository.
