I was looking at this bug today and wanted to clarify some points.

1) s = 'org.gnome.Epiphany.PrivateBrowsing' ??

2) So ({sE}) means each blacklist template associated with the application which set it

3) RemoveTemplate(s) would clear all the blacklists set by an application. Should not it be RemoveTemplate(s, E) or RemoveTemplate(s, {E}) meaning clearing more than one event template at a time

4) Similarly, how about AddTemplate(s, {E}) meaning adding more than one template at a time

Have some more doubts on Changed() but will ask them after these 4 doubts are cleared.
