Comment(by davidloeffler):
It is necessary because the arithmetic subgroup init routine now calls {{{
Group.__init__ }}}, which was not previously the case. The group init
routine subsequently calls various other init routines that link
arithmetic subgroups into Sage's category framework, with all of its
baroque subtleties involving dynamic classes etc.
