Asian shares had a muted session Friday as Greek debt talks took yet another confusing turn, while the dollar held firm in the wake of reassuringly upbeat U.S. retail data. Activity was sparse with MSCI’s index of Asia-Pacific shares outside Japan up 0.2 percent, but only just above three-month lows. Japan’s Nikkei (.N225) barely budged, though it found some support in a dollar bounce against the yen.
