demandimport: enforce ignore list while processing modules in fromlist If a module is loaded as "from . import x" form, there has been no way to disable demand loading for that module because name is ''. This patch makes it possible to prevent demand loading by '<package-name>.x'. We don't use _hgextimport(_origimport) here since attr is known to be a sub-module name. Adding hgext_ to attr wouldn't make sense.
