If one slept in a tallit overnight, must one recite a new blessing in the morning without removing and re-wearing it?

Synopsis

The Mechaber rules a new blessing is required in the morning even without removing the tallit, since nighttime interrupts the obligation (night is not a time for tzitzit). The Taz and Beur HaGra question this but accept it. The Magen Avraham (citing Bach) says no blessing is required. The Aruch HaShulchan distinguishes between the positions of the Tur (no blessing) and the Rosh's responsum (blessing required).
